Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17724, here are decompositions:

  • 11 + 17713 = 17724
  • 17 + 17707 = 17724
  • 41 + 17683 = 17724
  • 43 + 17681 = 17724
  • 67 + 17657 = 17724
  • 97 + 17627 = 17724
  • 101 + 17623 = 17724
  • 127 + 17597 = 17724

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17724 first appears in π at position 25,761 of the decimal expansion (the 25,761ordinal-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.
