Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15896, here are decompositions:

  • 7 + 15889 = 15896
  • 19 + 15877 = 15896
  • 37 + 15859 = 15896
  • 73 + 15823 = 15896
  • 79 + 15817 = 15896
  • 109 + 15787 = 15896
  • 157 + 15739 = 15896
  • 163 + 15733 = 15896

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15896 first appears in π at position 26,078 of the decimal expansion (the 26,078ordinal-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.
