Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71742, here are decompositions:

  • 23 + 71719 = 71742
  • 29 + 71713 = 71742
  • 31 + 71711 = 71742
  • 43 + 71699 = 71742
  • 71 + 71671 = 71742
  • 79 + 71663 = 71742
  • 109 + 71633 = 71742
  • 149 + 71593 = 71742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71742 first appears in π at position 36,727 of the decimal expansion (the 36,727ordinal-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.
