Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610, here are decompositions:

  • 3 + 31607 = 31610
  • 37 + 31573 = 31610
  • 43 + 31567 = 31610
  • 67 + 31543 = 31610
  • 79 + 31531 = 31610
  • 97 + 31513 = 31610
  • 223 + 31387 = 31610
  • 277 + 31333 = 31610

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31610 first appears in π at position 274,355 of the decimal expansion (the 274,355ordinal-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.
