Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22510, here are decompositions:

  • 29 + 22481 = 22510
  • 41 + 22469 = 22510
  • 101 + 22409 = 22510
  • 113 + 22397 = 22510
  • 167 + 22343 = 22510
  • 227 + 22283 = 22510
  • 233 + 22277 = 22510
  • 239 + 22271 = 22510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22510 first appears in π at position 75,679 of the decimal expansion (the 75,679ordinal-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.
