Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27946, here are decompositions:

  • 3 + 27943 = 27946
  • 5 + 27941 = 27946
  • 29 + 27917 = 27946
  • 53 + 27893 = 27946
  • 137 + 27809 = 27946
  • 167 + 27779 = 27946
  • 173 + 27773 = 27946
  • 179 + 27767 = 27946

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27946 first appears in π at position 185,730 of the decimal expansion (the 185,730ordinal-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.
