Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8986, here are decompositions:

  • 17 + 8969 = 8986
  • 23 + 8963 = 8986
  • 53 + 8933 = 8986
  • 137 + 8849 = 8986
  • 149 + 8837 = 8986
  • 167 + 8819 = 8986
  • 179 + 8807 = 8986
  • 233 + 8753 = 8986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8986 first appears in π at position 4,665 of the decimal expansion (the 4,665ordinal-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.
