Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25576, here are decompositions:

  • 53 + 25523 = 25576
  • 107 + 25469 = 25576
  • 113 + 25463 = 25576
  • 137 + 25439 = 25576
  • 167 + 25409 = 25576
  • 227 + 25349 = 25576
  • 233 + 25343 = 25576
  • 269 + 25307 = 25576

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25576 first appears in π at position 241,115 of the decimal expansion (the 241,115ordinal-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.
