Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86670, here are decompositions:

  • 41 + 86629 = 86670
  • 43 + 86627 = 86670
  • 71 + 86599 = 86670
  • 83 + 86587 = 86670
  • 97 + 86573 = 86670
  • 109 + 86561 = 86670
  • 131 + 86539 = 86670
  • 137 + 86533 = 86670

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86670 first appears in π at position 163,337 of the decimal expansion (the 163,337ordinal-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.
