Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65886, here are decompositions:

  • 5 + 65881 = 65886
  • 19 + 65867 = 65886
  • 43 + 65843 = 65886
  • 47 + 65839 = 65886
  • 59 + 65827 = 65886
  • 97 + 65789 = 65886
  • 109 + 65777 = 65886
  • 157 + 65729 = 65886

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65886 first appears in π at position 43,877 of the decimal expansion (the 43,877ordinal-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.
