Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17540, here are decompositions:

  • 31 + 17509 = 17540
  • 43 + 17497 = 17540
  • 73 + 17467 = 17540
  • 97 + 17443 = 17540
  • 109 + 17431 = 17540
  • 139 + 17401 = 17540
  • 151 + 17389 = 17540
  • 157 + 17383 = 17540

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17540 first appears in π at position 204,660 of the decimal expansion (the 204,660ordinal-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.
