Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25498, here are decompositions:

  • 29 + 25469 = 25498
  • 41 + 25457 = 25498
  • 59 + 25439 = 25498
  • 89 + 25409 = 25498
  • 107 + 25391 = 25498
  • 131 + 25367 = 25498
  • 149 + 25349 = 25498
  • 191 + 25307 = 25498

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25498 first appears in π at position 113,582 of the decimal expansion (the 113,582ordinal-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.
