Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25748, here are decompositions:

  • 7 + 25741 = 25748
  • 31 + 25717 = 25748
  • 109 + 25639 = 25748
  • 127 + 25621 = 25748
  • 139 + 25609 = 25748
  • 211 + 25537 = 25748
  • 277 + 25471 = 25748
  • 337 + 25411 = 25748

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25748 first appears in π at position 28,617 of the decimal expansion (the 28,617ordinal-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.
