Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25190, here are decompositions:

  • 7 + 25183 = 25190
  • 19 + 25171 = 25190
  • 37 + 25153 = 25190
  • 43 + 25147 = 25190
  • 73 + 25117 = 25190
  • 79 + 25111 = 25190
  • 103 + 25087 = 25190
  • 157 + 25033 = 25190

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25190 first appears in π at position 275,808 of the decimal expansion (the 275,808ordinal-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.
