Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22278, here are decompositions:

  • 5 + 22273 = 22278
  • 7 + 22271 = 22278
  • 19 + 22259 = 22278
  • 31 + 22247 = 22278
  • 89 + 22189 = 22278
  • 107 + 22171 = 22278
  • 131 + 22147 = 22278
  • 149 + 22129 = 22278

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22278 first appears in π at position 119,813 of the decimal expansion (the 119,813ordinal-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.
