Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86658, here are decompositions:

  • 29 + 86629 = 86658
  • 31 + 86627 = 86658
  • 59 + 86599 = 86658
  • 71 + 86587 = 86658
  • 79 + 86579 = 86658
  • 97 + 86561 = 86658
  • 127 + 86531 = 86658
  • 149 + 86509 = 86658

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86658 first appears in π at position 46,777 of the decimal expansion (the 46,777ordinal-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.
