Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17644, here are decompositions:

  • 17 + 17627 = 17644
  • 47 + 17597 = 17644
  • 71 + 17573 = 17644
  • 167 + 17477 = 17644
  • 173 + 17471 = 17644
  • 227 + 17417 = 17644
  • 251 + 17393 = 17644
  • 257 + 17387 = 17644

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17644 first appears in π at position 98,659 of the decimal expansion (the 98,659ordinal-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.
