Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17788, here are decompositions:

  • 5 + 17783 = 17788
  • 41 + 17747 = 17788
  • 59 + 17729 = 17788
  • 107 + 17681 = 17788
  • 131 + 17657 = 17788
  • 179 + 17609 = 17788
  • 191 + 17597 = 17788
  • 269 + 17519 = 17788

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17788 first appears in π at position 25,138 of the decimal expansion (the 25,138ordinal-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.
