Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23936, here are decompositions:

  • 7 + 23929 = 23936
  • 19 + 23917 = 23936
  • 37 + 23899 = 23936
  • 43 + 23893 = 23936
  • 67 + 23869 = 23936
  • 79 + 23857 = 23936
  • 103 + 23833 = 23936
  • 109 + 23827 = 23936

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23936 first appears in π at position 68,725 of the decimal expansion (the 68,725ordinal-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.
