Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22558, here are decompositions:

  • 17 + 22541 = 22558
  • 47 + 22511 = 22558
  • 89 + 22469 = 22558
  • 149 + 22409 = 22558
  • 167 + 22391 = 22558
  • 191 + 22367 = 22558
  • 251 + 22307 = 22558
  • 281 + 22277 = 22558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22558 first appears in π at position 61,947 of the decimal expansion (the 61,947ordinal-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.
