Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483208, here are decompositions:

  • 139 + 31483069 = 31483208
  • 157 + 31483051 = 31483208
  • 349 + 31482859 = 31483208
  • 409 + 31482799 = 31483208
  • 499 + 31482709 = 31483208
  • 541 + 31482667 = 31483208
  • 577 + 31482631 = 31483208
  • 709 + 31482499 = 31483208

Showing the first eight; more decompositions exist.
