Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498480, here are decompositions:

  • 31 + 2147498449 = 2147498480
  • 67 + 2147498413 = 2147498480
  • 139 + 2147498341 = 2147498480
  • 271 + 2147498209 = 2147498480
  • 541 + 2147497939 = 2147498480
  • 709 + 2147497771 = 2147498480
  • 991 + 2147497489 = 2147498480
  • 1021 + 2147497459 = 2147498480

Showing the first eight; more decompositions exist.
