Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498420, here are decompositions:

  • 7 + 2147498413 = 2147498420
  • 73 + 2147498347 = 2147498420
  • 79 + 2147498341 = 2147498420
  • 211 + 2147498209 = 2147498420
  • 241 + 2147498179 = 2147498420
  • 499 + 2147497921 = 2147498420
  • 757 + 2147497663 = 2147498420
  • 1009 + 2147497411 = 2147498420

Showing the first eight; more decompositions exist.
