Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86630, here are decompositions:

  • 3 + 86627 = 86630
  • 31 + 86599 = 86630
  • 43 + 86587 = 86630
  • 97 + 86533 = 86630
  • 139 + 86491 = 86630
  • 163 + 86467 = 86630
  • 241 + 86389 = 86630
  • 277 + 86353 = 86630

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86630 first appears in π at position 77,384 of the decimal expansion (the 77,384ordinal-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.
