Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27772, here are decompositions:

  • 5 + 27767 = 27772
  • 23 + 27749 = 27772
  • 29 + 27743 = 27772
  • 71 + 27701 = 27772
  • 83 + 27689 = 27772
  • 191 + 27581 = 27772
  • 233 + 27539 = 27772
  • 263 + 27509 = 27772

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27772 first appears in π at position 19,902 of the decimal expansion (the 19,902ordinal-suffix:nd 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.
