Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8864, here are decompositions:

  • 3 + 8861 = 8864
  • 43 + 8821 = 8864
  • 61 + 8803 = 8864
  • 103 + 8761 = 8864
  • 127 + 8737 = 8864
  • 151 + 8713 = 8864
  • 157 + 8707 = 8864
  • 223 + 8641 = 8864

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8864 first appears in π at position 2,384 of the decimal expansion (the 2,384ordinal-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.
