Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19776, here are decompositions:

  • 13 + 19763 = 19776
  • 17 + 19759 = 19776
  • 23 + 19753 = 19776
  • 37 + 19739 = 19776
  • 59 + 19717 = 19776
  • 67 + 19709 = 19776
  • 79 + 19697 = 19776
  • 89 + 19687 = 19776

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19776 first appears in π at position 177,965 of the decimal expansion (the 177,965ordinal-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.
