Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86864, here are decompositions:

  • 3 + 86861 = 86864
  • 7 + 86857 = 86864
  • 13 + 86851 = 86864
  • 97 + 86767 = 86864
  • 277 + 86587 = 86864
  • 331 + 86533 = 86864
  • 373 + 86491 = 86864
  • 397 + 86467 = 86864

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86864 first appears in π at position 47,614 of the decimal expansion (the 47,614ordinal-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.
