Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22782, here are decompositions:

  • 5 + 22777 = 22782
  • 13 + 22769 = 22782
  • 31 + 22751 = 22782
  • 41 + 22741 = 22782
  • 43 + 22739 = 22782
  • 61 + 22721 = 22782
  • 73 + 22709 = 22782
  • 83 + 22699 = 22782

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22782 first appears in π at position 149,996 of the decimal expansion (the 149,996ordinal-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.
