Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68018, here are decompositions:

  • 31 + 67987 = 68018
  • 61 + 67957 = 68018
  • 79 + 67939 = 68018
  • 127 + 67891 = 68018
  • 151 + 67867 = 68018
  • 199 + 67819 = 68018
  • 211 + 67807 = 68018
  • 229 + 67789 = 68018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68018 first appears in π at position 38,096 of the decimal expansion (the 38,096ordinal-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.
