Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10778, here are decompositions:

  • 7 + 10771 = 10778
  • 67 + 10711 = 10778
  • 127 + 10651 = 10778
  • 139 + 10639 = 10778
  • 151 + 10627 = 10778
  • 181 + 10597 = 10778
  • 211 + 10567 = 10778
  • 277 + 10501 = 10778

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10778 first appears in π at position 81,075 of the decimal expansion (the 81,075ordinal-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.
