Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10838, here are decompositions:

  • 7 + 10831 = 10838
  • 67 + 10771 = 10838
  • 109 + 10729 = 10838
  • 127 + 10711 = 10838
  • 151 + 10687 = 10838
  • 181 + 10657 = 10838
  • 199 + 10639 = 10838
  • 211 + 10627 = 10838

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 10838 first appears in π at position 77,580 of the decimal expansion (the 77,580ordinal-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.
