Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31342, here are decompositions:

  • 5 + 31337 = 31342
  • 23 + 31319 = 31342
  • 71 + 31271 = 31342
  • 83 + 31259 = 31342
  • 89 + 31253 = 31342
  • 149 + 31193 = 31342
  • 191 + 31151 = 31342
  • 251 + 31091 = 31342

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31342 first appears in π at position 49,812 of the decimal expansion (the 49,812ordinal-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.
