Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483800, here are decompositions:

  • 11 + 31483789 = 31483800
  • 41 + 31483759 = 31483800
  • 67 + 31483733 = 31483800
  • 109 + 31483691 = 31483800
  • 137 + 31483663 = 31483800
  • 151 + 31483649 = 31483800
  • 223 + 31483577 = 31483800
  • 251 + 31483549 = 31483800

Showing the first eight; more decompositions exist.
