Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19560, here are decompositions:

  • 7 + 19553 = 19560
  • 17 + 19543 = 19560
  • 19 + 19541 = 19560
  • 29 + 19531 = 19560
  • 53 + 19507 = 19560
  • 59 + 19501 = 19560
  • 71 + 19489 = 19560
  • 83 + 19477 = 19560

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19560 first appears in π at position 56,614 of the decimal expansion (the 56,614ordinal-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.
