Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17778, here are decompositions:

  • 17 + 17761 = 17778
  • 29 + 17749 = 17778
  • 31 + 17747 = 17778
  • 41 + 17737 = 17778
  • 71 + 17707 = 17778
  • 97 + 17681 = 17778
  • 109 + 17669 = 17778
  • 151 + 17627 = 17778

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17778 first appears in π at position 503,528 of the decimal expansion (the 503,528ordinal-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.
