Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31632, here are decompositions:

  • 5 + 31627 = 31632
  • 31 + 31601 = 31632
  • 59 + 31573 = 31632
  • 89 + 31543 = 31632
  • 101 + 31531 = 31632
  • 151 + 31481 = 31632
  • 163 + 31469 = 31632
  • 239 + 31393 = 31632

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31632 first appears in π at position 34,996 of the decimal expansion (the 34,996ordinal-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.
