Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533260, here are decompositions:

  • 127 + 31533133 = 31533260
  • 163 + 31533097 = 31533260
  • 337 + 31532923 = 31533260
  • 379 + 31532881 = 31533260
  • 397 + 31532863 = 31533260
  • 523 + 31532737 = 31533260
  • 601 + 31532659 = 31533260
  • 607 + 31532653 = 31533260

Showing the first eight; more decompositions exist.
