Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86928, here are decompositions:

  • 5 + 86923 = 86928
  • 59 + 86869 = 86928
  • 67 + 86861 = 86928
  • 71 + 86857 = 86928
  • 157 + 86771 = 86928
  • 199 + 86729 = 86928
  • 239 + 86689 = 86928
  • 251 + 86677 = 86928

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86928 first appears in π at position 97,866 of the decimal expansion (the 97,866ordinal-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.
