Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498372, here are decompositions:

  • 31 + 2147498341 = 2147498372
  • 163 + 2147498209 = 2147498372
  • 193 + 2147498179 = 2147498372
  • 433 + 2147497939 = 2147498372
  • 601 + 2147497771 = 2147498372
  • 673 + 2147497699 = 2147498372
  • 709 + 2147497663 = 2147498372
  • 883 + 2147497489 = 2147498372

Showing the first eight; more decompositions exist.
