Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22470, here are decompositions:

  • 17 + 22453 = 22470
  • 23 + 22447 = 22470
  • 29 + 22441 = 22470
  • 37 + 22433 = 22470
  • 61 + 22409 = 22470
  • 73 + 22397 = 22470
  • 79 + 22391 = 22470
  • 89 + 22381 = 22470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22470 first appears in π at position 25,632 of the decimal expansion (the 25,632ordinal-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.
