Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22028, here are decompositions:

  • 31 + 21997 = 22028
  • 37 + 21991 = 22028
  • 67 + 21961 = 22028
  • 157 + 21871 = 22028
  • 211 + 21817 = 22028
  • 229 + 21799 = 22028
  • 241 + 21787 = 22028
  • 271 + 21757 = 22028

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22028 first appears in π at position 29,961 of the decimal expansion (the 29,961ordinal-suffix:st 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.
