Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15510, here are decompositions:

  • 13 + 15497 = 15510
  • 17 + 15493 = 15510
  • 37 + 15473 = 15510
  • 43 + 15467 = 15510
  • 59 + 15451 = 15510
  • 67 + 15443 = 15510
  • 71 + 15439 = 15510
  • 83 + 15427 = 15510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15510 first appears in π at position 308,232 of the decimal expansion (the 308,232ordinal-suffix:nd 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.
