Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15798, here are decompositions:

  • 7 + 15791 = 15798
  • 11 + 15787 = 15798
  • 31 + 15767 = 15798
  • 37 + 15761 = 15798
  • 59 + 15739 = 15798
  • 61 + 15737 = 15798
  • 67 + 15731 = 15798
  • 71 + 15727 = 15798

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15798 first appears in π at position 44,976 of the decimal expansion (the 44,976ordinal-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.
