Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15908, here are decompositions:

  • 7 + 15901 = 15908
  • 19 + 15889 = 15908
  • 31 + 15877 = 15908
  • 181 + 15727 = 15908
  • 229 + 15679 = 15908
  • 241 + 15667 = 15908
  • 307 + 15601 = 15908
  • 349 + 15559 = 15908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15908 first appears in π at position 42,897 of the decimal expansion (the 42,897ordinal-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.
