Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11930, here are decompositions:

  • 3 + 11927 = 11930
  • 7 + 11923 = 11930
  • 43 + 11887 = 11930
  • 67 + 11863 = 11930
  • 97 + 11833 = 11930
  • 103 + 11827 = 11930
  • 109 + 11821 = 11930
  • 151 + 11779 = 11930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11930 first appears in π at position 9,541 of the decimal expansion (the 9,541ordinal-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.
