Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497690, here are decompositions:

  • 29 + 2147497661 = 2147497690
  • 131 + 2147497559 = 2147497690
  • 167 + 2147497523 = 2147497690
  • 197 + 2147497493 = 2147497690
  • 557 + 2147497133 = 2147497690
  • 647 + 2147497043 = 2147497690
  • 719 + 2147496971 = 2147497690
  • 773 + 2147496917 = 2147497690

Showing the first eight; more decompositions exist.
