Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12798, here are decompositions:

  • 7 + 12791 = 12798
  • 17 + 12781 = 12798
  • 41 + 12757 = 12798
  • 59 + 12739 = 12798
  • 101 + 12697 = 12798
  • 109 + 12689 = 12798
  • 127 + 12671 = 12798
  • 139 + 12659 = 12798

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12798 first appears in π at position 174,868 of the decimal expansion (the 174,868ordinal-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.
