Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497890, here are decompositions:

  • 157 + 2147497733 = 2147497890
  • 173 + 2147497717 = 2147497890
  • 191 + 2147497699 = 2147497890
  • 193 + 2147497697 = 2147497890
  • 199 + 2147497691 = 2147497890
  • 227 + 2147497663 = 2147497890
  • 229 + 2147497661 = 2147497890
  • 331 + 2147497559 = 2147497890

Showing the first eight; more decompositions exist.
