Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25004, here are decompositions:

  • 37 + 24967 = 25004
  • 61 + 24943 = 25004
  • 97 + 24907 = 25004
  • 127 + 24877 = 25004
  • 157 + 24847 = 25004
  • 163 + 24841 = 25004
  • 211 + 24793 = 25004
  • 223 + 24781 = 25004

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25004 first appears in π at position 129,613 of the decimal expansion (the 129,613ordinal-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.
