Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22404, here are decompositions:

  • 7 + 22397 = 22404
  • 13 + 22391 = 22404
  • 23 + 22381 = 22404
  • 37 + 22367 = 22404
  • 61 + 22343 = 22404
  • 97 + 22307 = 22404
  • 101 + 22303 = 22404
  • 113 + 22291 = 22404

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22404 first appears in π at position 125,174 of the decimal expansion (the 125,174ordinal-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.
