Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12910, here are decompositions:

  • 3 + 12907 = 12910
  • 11 + 12899 = 12910
  • 17 + 12893 = 12910
  • 89 + 12821 = 12910
  • 101 + 12809 = 12910
  • 167 + 12743 = 12910
  • 197 + 12713 = 12910
  • 239 + 12671 = 12910

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12910 first appears in π at position 7,876 of the decimal expansion (the 7,876ordinal-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.
