Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27918, here are decompositions:

  • 17 + 27901 = 27918
  • 67 + 27851 = 27918
  • 71 + 27847 = 27918
  • 101 + 27817 = 27918
  • 109 + 27809 = 27918
  • 127 + 27791 = 27918
  • 139 + 27779 = 27918
  • 151 + 27767 = 27918

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27918 first appears in π at position 183,295 of the decimal expansion (the 183,295ordinal-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.
