Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22380, here are decompositions:

  • 11 + 22369 = 22380
  • 13 + 22367 = 22380
  • 31 + 22349 = 22380
  • 37 + 22343 = 22380
  • 73 + 22307 = 22380
  • 89 + 22291 = 22380
  • 97 + 22283 = 22380
  • 101 + 22279 = 22380

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22380 first appears in π at position 53,282 of the decimal expansion (the 53,282ordinal-suffix:nd 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.
