Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25318, here are decompositions:

  • 11 + 25307 = 25318
  • 17 + 25301 = 25318
  • 71 + 25247 = 25318
  • 89 + 25229 = 25318
  • 149 + 25169 = 25318
  • 191 + 25127 = 25318
  • 197 + 25121 = 25318
  • 281 + 25037 = 25318

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25318 first appears in π at position 33,479 of the decimal expansion (the 33,479ordinal-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.
