Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19576, here are decompositions:

  • 5 + 19571 = 19576
  • 17 + 19559 = 19576
  • 23 + 19553 = 19576
  • 107 + 19469 = 19576
  • 113 + 19463 = 19576
  • 149 + 19427 = 19576
  • 173 + 19403 = 19576
  • 197 + 19379 = 19576

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19576 first appears in π at position 15,159 of the decimal expansion (the 15,159ordinal-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.
