Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498456, here are decompositions:

  • 7 + 2147498449 = 2147498456
  • 43 + 2147498413 = 2147498456
  • 109 + 2147498347 = 2147498456
  • 277 + 2147498179 = 2147498456
  • 379 + 2147498077 = 2147498456
  • 739 + 2147497717 = 2147498456
  • 757 + 2147497699 = 2147498456
  • 967 + 2147497489 = 2147498456

Showing the first eight; more decompositions exist.
