Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7912, here are decompositions:

  • 5 + 7907 = 7912
  • 11 + 7901 = 7912
  • 29 + 7883 = 7912
  • 59 + 7853 = 7912
  • 71 + 7841 = 7912
  • 83 + 7829 = 7912
  • 89 + 7823 = 7912
  • 239 + 7673 = 7912

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7912 first appears in π at position 27,920 of the decimal expansion (the 27,920ordinal-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.
