Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12998, here are decompositions:

  • 19 + 12979 = 12998
  • 31 + 12967 = 12998
  • 79 + 12919 = 12998
  • 109 + 12889 = 12998
  • 157 + 12841 = 12998
  • 199 + 12799 = 12998
  • 241 + 12757 = 12998
  • 277 + 12721 = 12998

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12998 first appears in π at position 52,826 of the decimal expansion (the 52,826ordinal-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.
