Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86618, here are decompositions:

  • 19 + 86599 = 86618
  • 31 + 86587 = 86618
  • 79 + 86539 = 86618
  • 109 + 86509 = 86618
  • 127 + 86491 = 86618
  • 151 + 86467 = 86618
  • 157 + 86461 = 86618
  • 229 + 86389 = 86618

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86618 first appears in π at position 308,787 of the decimal expansion (the 308,787ordinal-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.
