Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532448, here are decompositions:

  • 11 + 31532437 = 31532448
  • 19 + 31532429 = 31532448
  • 47 + 31532401 = 31532448
  • 107 + 31532341 = 31532448
  • 109 + 31532339 = 31532448
  • 179 + 31532269 = 31532448
  • 229 + 31532219 = 31532448
  • 239 + 31532209 = 31532448

Showing the first eight; more decompositions exist.
