Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31636, here are decompositions:

  • 29 + 31607 = 31636
  • 53 + 31583 = 31636
  • 89 + 31547 = 31636
  • 167 + 31469 = 31636
  • 239 + 31397 = 31636
  • 257 + 31379 = 31636
  • 317 + 31319 = 31636
  • 359 + 31277 = 31636

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31636 first appears in π at position 25,115 of the decimal expansion (the 25,115ordinal-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.
