Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22436, here are decompositions:

  • 3 + 22433 = 22436
  • 67 + 22369 = 22436
  • 157 + 22279 = 22436
  • 163 + 22273 = 22436
  • 277 + 22159 = 22436
  • 283 + 22153 = 22436
  • 307 + 22129 = 22436
  • 313 + 22123 = 22436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22436 first appears in π at position 65,712 of the decimal expansion (the 65,712ordinal-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.
