Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23930, here are decompositions:

  • 13 + 23917 = 23930
  • 19 + 23911 = 23930
  • 31 + 23899 = 23930
  • 37 + 23893 = 23930
  • 43 + 23887 = 23930
  • 61 + 23869 = 23930
  • 73 + 23857 = 23930
  • 97 + 23833 = 23930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23930 first appears in π at position 19,607 of the decimal expansion (the 19,607ordinal-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.
