Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537786, here are decompositions:

  • 17 + 33537769 = 33537786
  • 19 + 33537767 = 33537786
  • 97 + 33537689 = 33537786
  • 103 + 33537683 = 33537786
  • 109 + 33537677 = 33537786
  • 173 + 33537613 = 33537786
  • 193 + 33537593 = 33537786
  • 197 + 33537589 = 33537786

Showing the first eight; more decompositions exist.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 33537786 first appears in π at position 675,565 of the decimal expansion (the 675,565ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
