Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27756, here are decompositions:

  • 5 + 27751 = 27756
  • 7 + 27749 = 27756
  • 13 + 27743 = 27756
  • 17 + 27739 = 27756
  • 19 + 27737 = 27756
  • 23 + 27733 = 27756
  • 59 + 27697 = 27756
  • 67 + 27689 = 27756

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27756 first appears in π at position 8,564 of the decimal expansion (the 8,564ordinal-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.
