Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508016, here are decompositions:

  • 13 + 31508003 = 31508016
  • 103 + 31507913 = 31508016
  • 139 + 31507877 = 31508016
  • 179 + 31507837 = 31508016
  • 193 + 31507823 = 31508016
  • 223 + 31507793 = 31508016
  • 227 + 31507789 = 31508016
  • 229 + 31507787 = 31508016

Showing the first eight; more decompositions exist.
