Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 50640, here are decompositions:

  • 13 + 50627 = 50640
  • 41 + 50599 = 50640
  • 47 + 50593 = 50640
  • 53 + 50587 = 50640
  • 59 + 50581 = 50640
  • 89 + 50551 = 50640
  • 97 + 50543 = 50640
  • 101 + 50539 = 50640

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 50640 first appears in π at position 94,374 of the decimal expansion (the 94,374ordinal-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.
