Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516048, here are decompositions:

  • 41 + 31516007 = 31516048
  • 59 + 31515989 = 31516048
  • 107 + 31515941 = 31516048
  • 149 + 31515899 = 31516048
  • 167 + 31515881 = 31516048
  • 191 + 31515857 = 31516048
  • 227 + 31515821 = 31516048
  • 281 + 31515767 = 31516048

Showing the first eight; more decompositions exist.
