Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86828, here are decompositions:

  • 61 + 86767 = 86828
  • 109 + 86719 = 86828
  • 139 + 86689 = 86828
  • 151 + 86677 = 86828
  • 199 + 86629 = 86828
  • 229 + 86599 = 86828
  • 241 + 86587 = 86828
  • 337 + 86491 = 86828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86828 first appears in π at position 57,002 of the decimal expansion (the 57,002ordinal-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.
