Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519422, here are decompositions:

  • 5 + 31519417 = 31519422
  • 19 + 31519403 = 31519422
  • 41 + 31519381 = 31519422
  • 43 + 31519379 = 31519422
  • 59 + 31519363 = 31519422
  • 101 + 31519321 = 31519422
  • 211 + 31519211 = 31519422
  • 223 + 31519199 = 31519422

Showing the first eight; more decompositions exist.
