Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678, here are decompositions:

  • 31 + 8647 = 8678
  • 37 + 8641 = 8678
  • 79 + 8599 = 8678
  • 97 + 8581 = 8678
  • 139 + 8539 = 8678
  • 151 + 8527 = 8678
  • 157 + 8521 = 8678
  • 211 + 8467 = 8678

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8678 first appears in π at position 233 of the decimal expansion (the 233ordinal-suffix:rd 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.
