Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622090, here are decompositions:

  • 43 + 31622047 = 31622090
  • 109 + 31621981 = 31622090
  • 127 + 31621963 = 31622090
  • 193 + 31621897 = 31622090
  • 211 + 31621879 = 31622090
  • 337 + 31621753 = 31622090
  • 397 + 31621693 = 31622090
  • 421 + 31621669 = 31622090

Showing the first eight; more decompositions exist.
