Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68286, here are decompositions:

  • 5 + 68281 = 68286
  • 7 + 68279 = 68286
  • 47 + 68239 = 68286
  • 59 + 68227 = 68286
  • 67 + 68219 = 68286
  • 73 + 68213 = 68286
  • 79 + 68207 = 68286
  • 139 + 68147 = 68286

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68286 first appears in π at position 74,262 of the decimal expansion (the 74,262ordinal-suffix:nd 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.
