Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17380, here are decompositions:

  • 3 + 17377 = 17380
  • 29 + 17351 = 17380
  • 47 + 17333 = 17380
  • 53 + 17327 = 17380
  • 59 + 17321 = 17380
  • 89 + 17291 = 17380
  • 149 + 17231 = 17380
  • 173 + 17207 = 17380

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17380 first appears in π at position 67,627 of the decimal expansion (the 67,627ordinal-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.
