Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22742, here are decompositions:

  • 3 + 22739 = 22742
  • 43 + 22699 = 22742
  • 73 + 22669 = 22742
  • 103 + 22639 = 22742
  • 193 + 22549 = 22742
  • 199 + 22543 = 22742
  • 211 + 22531 = 22742
  • 241 + 22501 = 22742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22742 first appears in π at position 8,799 of the decimal expansion (the 8,799ordinal-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.
