Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15486, here are decompositions:

  • 13 + 15473 = 15486
  • 19 + 15467 = 15486
  • 43 + 15443 = 15486
  • 47 + 15439 = 15486
  • 59 + 15427 = 15486
  • 73 + 15413 = 15486
  • 103 + 15383 = 15486
  • 109 + 15377 = 15486

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15486 first appears in π at position 66,741 of the decimal expansion (the 66,741ordinal-suffix:st 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.
