Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78510, here are decompositions:

  • 13 + 78497 = 78510
  • 23 + 78487 = 78510
  • 31 + 78479 = 78510
  • 43 + 78467 = 78510
  • 71 + 78439 = 78510
  • 73 + 78437 = 78510
  • 83 + 78427 = 78510
  • 109 + 78401 = 78510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78510 first appears in π at position 126,169 of the decimal expansion (the 126,169ordinal-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.
