Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25228, here are decompositions:

  • 59 + 25169 = 25228
  • 101 + 25127 = 25228
  • 107 + 25121 = 25228
  • 131 + 25097 = 25228
  • 191 + 25037 = 25228
  • 197 + 25031 = 25228
  • 239 + 24989 = 25228
  • 251 + 24977 = 25228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25228 first appears in π at position 2,525 of the decimal expansion (the 2,525ordinal-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.
