Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498378, here are decompositions:

  • 31 + 2147498347 = 2147498378
  • 37 + 2147498341 = 2147498378
  • 199 + 2147498179 = 2147498378
  • 439 + 2147497939 = 2147498378
  • 457 + 2147497921 = 2147498378
  • 607 + 2147497771 = 2147498378
  • 661 + 2147497717 = 2147498378
  • 919 + 2147497459 = 2147498378

Showing the first eight; more decompositions exist.
