Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31436, here are decompositions:

  • 43 + 31393 = 31436
  • 79 + 31357 = 31436
  • 103 + 31333 = 31436
  • 109 + 31327 = 31436
  • 199 + 31237 = 31436
  • 277 + 31159 = 31436
  • 283 + 31153 = 31436
  • 313 + 31123 = 31436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31436 first appears in π at position 197,551 of the decimal expansion (the 197,551ordinal-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.
