Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25144, here are decompositions:

  • 17 + 25127 = 25144
  • 23 + 25121 = 25144
  • 47 + 25097 = 25144
  • 71 + 25073 = 25144
  • 107 + 25037 = 25144
  • 113 + 25031 = 25144
  • 131 + 25013 = 25144
  • 167 + 24977 = 25144

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25144 first appears in π at position 119,557 of the decimal expansion (the 119,557ordinal-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.
