Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25868, here are decompositions:

  • 19 + 25849 = 25868
  • 67 + 25801 = 25868
  • 97 + 25771 = 25868
  • 109 + 25759 = 25868
  • 127 + 25741 = 25868
  • 151 + 25717 = 25868
  • 211 + 25657 = 25868
  • 229 + 25639 = 25868

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25868 first appears in π at position 98,355 of the decimal expansion (the 98,355ordinal-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.
