Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 34640, here are decompositions:

  • 37 + 34603 = 34640
  • 97 + 34543 = 34640
  • 103 + 34537 = 34640
  • 127 + 34513 = 34640
  • 139 + 34501 = 34640
  • 157 + 34483 = 34640
  • 211 + 34429 = 34640
  • 271 + 34369 = 34640

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 34640 first appears in π at position 259,558 of the decimal expansion (the 259,558ordinal-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.
