Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598, here are decompositions:

  • 31 + 31567 = 31598
  • 67 + 31531 = 31598
  • 109 + 31489 = 31598
  • 211 + 31387 = 31598
  • 241 + 31357 = 31598
  • 271 + 31327 = 31598
  • 277 + 31321 = 31598
  • 331 + 31267 = 31598

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31598 first appears in π at position 5,022 of the decimal expansion (the 5,022ordinal-suffix:nd 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.
