Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6386, here are decompositions:

  • 7 + 6379 = 6386
  • 13 + 6373 = 6386
  • 19 + 6367 = 6386
  • 43 + 6343 = 6386
  • 109 + 6277 = 6386
  • 139 + 6247 = 6386
  • 157 + 6229 = 6386
  • 223 + 6163 = 6386

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6386 first appears in π at position 17,478 of the decimal expansion (the 17,478ordinal-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.
