Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8868, here are decompositions:

  • 5 + 8863 = 8868
  • 7 + 8861 = 8868
  • 19 + 8849 = 8868
  • 29 + 8839 = 8868
  • 31 + 8837 = 8868
  • 37 + 8831 = 8868
  • 47 + 8821 = 8868
  • 61 + 8807 = 8868

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8868 first appears in π at position 4,986 of the decimal expansion (the 4,986ordinal-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.
