Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498474, here are decompositions:

  • 3 + 2147498471 = 2147498474
  • 61 + 2147498413 = 2147498474
  • 127 + 2147498347 = 2147498474
  • 397 + 2147498077 = 2147498474
  • 757 + 2147497717 = 2147498474
  • 811 + 2147497663 = 2147498474
  • 967 + 2147497507 = 2147498474
  • 1063 + 2147497411 = 2147498474

Showing the first eight; more decompositions exist.
