Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68312, here are decompositions:

  • 31 + 68281 = 68312
  • 73 + 68239 = 68312
  • 103 + 68209 = 68312
  • 151 + 68161 = 68312
  • 199 + 68113 = 68312
  • 241 + 68071 = 68312
  • 271 + 68041 = 68312
  • 373 + 67939 = 68312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68312 first appears in π at position 158,101 of the decimal expansion (the 158,101ordinal-suffix:st 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.
