Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47986, here are decompositions:

  • 5 + 47981 = 47986
  • 17 + 47969 = 47986
  • 23 + 47963 = 47986
  • 47 + 47939 = 47986
  • 53 + 47933 = 47986
  • 83 + 47903 = 47986
  • 149 + 47837 = 47986
  • 167 + 47819 = 47986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47986 first appears in π at position 89,062 of the decimal expansion (the 89,062ordinal-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.
