Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15526, here are decompositions:

  • 29 + 15497 = 15526
  • 53 + 15473 = 15526
  • 59 + 15467 = 15526
  • 83 + 15443 = 15526
  • 113 + 15413 = 15526
  • 149 + 15377 = 15526
  • 167 + 15359 = 15526
  • 197 + 15329 = 15526

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15526 first appears in π at position 115,637 of the decimal expansion (the 115,637ordinal-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.
