Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71616, here are decompositions:

  • 19 + 71597 = 71616
  • 23 + 71593 = 71616
  • 47 + 71569 = 71616
  • 53 + 71563 = 71616
  • 67 + 71549 = 71616
  • 79 + 71537 = 71616
  • 89 + 71527 = 71616
  • 113 + 71503 = 71616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71616 first appears in π at position 210,266 of the decimal expansion (the 210,266ordinal-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.
