Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64386, here are decompositions:

  • 5 + 64381 = 64386
  • 13 + 64373 = 64386
  • 53 + 64333 = 64386
  • 59 + 64327 = 64386
  • 67 + 64319 = 64386
  • 83 + 64303 = 64386
  • 103 + 64283 = 64386
  • 107 + 64279 = 64386

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64386 first appears in π at position 41,238 of the decimal expansion (the 41,238ordinal-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.
