Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25898, here are decompositions:

  • 31 + 25867 = 25898
  • 79 + 25819 = 25898
  • 97 + 25801 = 25898
  • 127 + 25771 = 25898
  • 139 + 25759 = 25898
  • 151 + 25747 = 25898
  • 157 + 25741 = 25898
  • 181 + 25717 = 25898

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25898 first appears in π at position 126,368 of the decimal expansion (the 126,368ordinal-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.
