Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65018, here are decompositions:

  • 7 + 65011 = 65018
  • 67 + 64951 = 65018
  • 97 + 64921 = 65018
  • 127 + 64891 = 65018
  • 139 + 64879 = 65018
  • 271 + 64747 = 65018
  • 397 + 64621 = 65018
  • 409 + 64609 = 65018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65018 first appears in π at position 223,195 of the decimal expansion (the 223,195ordinal-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.
