Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17518, here are decompositions:

  • 29 + 17489 = 17518
  • 41 + 17477 = 17518
  • 47 + 17471 = 17518
  • 101 + 17417 = 17518
  • 131 + 17387 = 17518
  • 167 + 17351 = 17518
  • 191 + 17327 = 17518
  • 197 + 17321 = 17518

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17518 first appears in π at position 4,626 of the decimal expansion (the 4,626ordinal-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.
