Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31232, here are decompositions:

  • 13 + 31219 = 31232
  • 43 + 31189 = 31232
  • 73 + 31159 = 31232
  • 79 + 31153 = 31232
  • 109 + 31123 = 31232
  • 151 + 31081 = 31232
  • 163 + 31069 = 31232
  • 181 + 31051 = 31232

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31232 first appears in π at position 49,253 of the decimal expansion (the 49,253ordinal-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.
