Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22140, here are decompositions:

  • 7 + 22133 = 22140
  • 11 + 22129 = 22140
  • 17 + 22123 = 22140
  • 29 + 22111 = 22140
  • 31 + 22109 = 22140
  • 47 + 22093 = 22140
  • 61 + 22079 = 22140
  • 67 + 22073 = 22140

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22140 first appears in π at position 192,257 of the decimal expansion (the 192,257ordinal-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.
