Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19594, here are decompositions:

  • 11 + 19583 = 19594
  • 17 + 19577 = 19594
  • 23 + 19571 = 19594
  • 41 + 19553 = 19594
  • 53 + 19541 = 19594
  • 131 + 19463 = 19594
  • 137 + 19457 = 19594
  • 167 + 19427 = 19594

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19594 first appears in π at position 78,801 of the decimal expansion (the 78,801ordinal-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.
