Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594198, here are decompositions:

  • 5 + 31594193 = 31594198
  • 47 + 31594151 = 31594198
  • 101 + 31594097 = 31594198
  • 137 + 31594061 = 31594198
  • 149 + 31594049 = 31594198
  • 239 + 31593959 = 31594198
  • 359 + 31593839 = 31594198
  • 401 + 31593797 = 31594198

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31594198 first appears in π at position 160,653 of the decimal expansion (the 160,653ordinal-suffix:rd 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.
