Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71636, here are decompositions:

  • 3 + 71633 = 71636
  • 43 + 71593 = 71636
  • 67 + 71569 = 71636
  • 73 + 71563 = 71636
  • 109 + 71527 = 71636
  • 157 + 71479 = 71636
  • 163 + 71473 = 71636
  • 193 + 71443 = 71636

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71636 first appears in π at position 135,284 of the decimal expansion (the 135,284ordinal-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.
