Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23688, here are decompositions:

  • 11 + 23677 = 23688
  • 17 + 23671 = 23688
  • 19 + 23669 = 23688
  • 59 + 23629 = 23688
  • 61 + 23627 = 23688
  • 79 + 23609 = 23688
  • 89 + 23599 = 23688
  • 107 + 23581 = 23688

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23688 first appears in π at position 29,894 of the decimal expansion (the 29,894ordinal-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.
