Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61874, here are decompositions:

  • 3 + 61871 = 61874
  • 13 + 61861 = 61874
  • 31 + 61843 = 61874
  • 37 + 61837 = 61874
  • 61 + 61813 = 61874
  • 151 + 61723 = 61874
  • 157 + 61717 = 61874
  • 193 + 61681 = 61874

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 61874 first appears in π at position 268,088 of the decimal expansion (the 268,088ordinal-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.
