Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19756, here are decompositions:

  • 3 + 19753 = 19756
  • 5 + 19751 = 19756
  • 17 + 19739 = 19756
  • 29 + 19727 = 19756
  • 47 + 19709 = 19756
  • 59 + 19697 = 19756
  • 173 + 19583 = 19756
  • 179 + 19577 = 19756

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19756 first appears in π at position 23,136 of the decimal expansion (the 23,136ordinal-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.
