Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71646, here are decompositions:

  • 13 + 71633 = 71646
  • 53 + 71593 = 71646
  • 83 + 71563 = 71646
  • 97 + 71549 = 71646
  • 109 + 71537 = 71646
  • 163 + 71483 = 71646
  • 167 + 71479 = 71646
  • 173 + 71473 = 71646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71646 first appears in π at position 9,634 of the decimal expansion (the 9,634ordinal-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.
