Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11938, here are decompositions:

  • 5 + 11933 = 11938
  • 11 + 11927 = 11938
  • 29 + 11909 = 11938
  • 41 + 11897 = 11938
  • 71 + 11867 = 11938
  • 107 + 11831 = 11938
  • 131 + 11807 = 11938
  • 137 + 11801 = 11938

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11938 first appears in π at position 106,231 of the decimal expansion (the 106,231ordinal-suffix:st 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.
