Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12916, here are decompositions:

  • 5 + 12911 = 12916
  • 17 + 12899 = 12916
  • 23 + 12893 = 12916
  • 107 + 12809 = 12916
  • 173 + 12743 = 12916
  • 227 + 12689 = 12916
  • 257 + 12659 = 12916
  • 263 + 12653 = 12916

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12916 first appears in π at position 30,944 of the decimal expansion (the 30,944ordinal-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.
