Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17750, here are decompositions:

  • 3 + 17747 = 17750
  • 13 + 17737 = 17750
  • 37 + 17713 = 17750
  • 43 + 17707 = 17750
  • 67 + 17683 = 17750
  • 127 + 17623 = 17750
  • 151 + 17599 = 17750
  • 181 + 17569 = 17750

Showing the first eight; more decompositions exist.

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 17750 first appears in π at position 212,299 of the decimal expansion (the 212,299ordinal-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.
