Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82868, here are decompositions:

  • 31 + 82837 = 82868
  • 109 + 82759 = 82868
  • 139 + 82729 = 82868
  • 211 + 82657 = 82868
  • 277 + 82591 = 82868
  • 307 + 82561 = 82868
  • 337 + 82531 = 82868
  • 397 + 82471 = 82868

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82868 first appears in π at position 273,030 of the decimal expansion (the 273,030ordinal-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.
