Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22880, here are decompositions:

  • 3 + 22877 = 22880
  • 19 + 22861 = 22880
  • 73 + 22807 = 22880
  • 97 + 22783 = 22880
  • 103 + 22777 = 22880
  • 139 + 22741 = 22880
  • 163 + 22717 = 22880
  • 181 + 22699 = 22880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22880 first appears in π at position 224,780 of the decimal expansion (the 224,780ordinal-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.
