Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22458, here are decompositions:

  • 5 + 22453 = 22458
  • 11 + 22447 = 22458
  • 17 + 22441 = 22458
  • 61 + 22397 = 22458
  • 67 + 22391 = 22458
  • 89 + 22369 = 22458
  • 109 + 22349 = 22458
  • 151 + 22307 = 22458

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22458 first appears in π at position 83,271 of the decimal expansion (the 83,271ordinal-suffix:st 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.
