Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31746, here are decompositions:

  • 5 + 31741 = 31746
  • 17 + 31729 = 31746
  • 19 + 31727 = 31746
  • 23 + 31723 = 31746
  • 47 + 31699 = 31746
  • 59 + 31687 = 31746
  • 79 + 31667 = 31746
  • 83 + 31663 = 31746

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31746 first appears in π at position 281,831 of the decimal expansion (the 281,831ordinal-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.
