Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27668, here are decompositions:

  • 37 + 27631 = 27668
  • 127 + 27541 = 27668
  • 139 + 27529 = 27668
  • 181 + 27487 = 27668
  • 211 + 27457 = 27668
  • 241 + 27427 = 27668
  • 271 + 27397 = 27668
  • 307 + 27361 = 27668

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27668 first appears in π at position 8,940 of the decimal expansion (the 8,940ordinal-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.
