Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550192, here are decompositions:

  • 13 + 31550179 = 31550192
  • 43 + 31550149 = 31550192
  • 61 + 31550131 = 31550192
  • 73 + 31550119 = 31550192
  • 211 + 31549981 = 31550192
  • 229 + 31549963 = 31550192
  • 313 + 31549879 = 31550192
  • 439 + 31549753 = 31550192

Showing the first eight; more decompositions exist.
