Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22506, here are decompositions:

  • 5 + 22501 = 22506
  • 23 + 22483 = 22506
  • 37 + 22469 = 22506
  • 53 + 22453 = 22506
  • 59 + 22447 = 22506
  • 73 + 22433 = 22506
  • 97 + 22409 = 22506
  • 109 + 22397 = 22506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22506 first appears in π at position 13,608 of the decimal expansion (the 13,608ordinal-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.
