Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23664, here are decompositions:

  • 31 + 23633 = 23664
  • 37 + 23627 = 23664
  • 41 + 23623 = 23664
  • 61 + 23603 = 23664
  • 71 + 23593 = 23664
  • 83 + 23581 = 23664
  • 97 + 23567 = 23664
  • 101 + 23563 = 23664

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23664 first appears in π at position 30,360 of the decimal expansion (the 30,360ordinal-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.
