Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498246, here are decompositions:

  • 37 + 2147498209 = 2147498246
  • 67 + 2147498179 = 2147498246
  • 307 + 2147497939 = 2147498246
  • 547 + 2147497699 = 2147498246
  • 739 + 2147497507 = 2147498246
  • 757 + 2147497489 = 2147498246
  • 787 + 2147497459 = 2147498246
  • 853 + 2147497393 = 2147498246

Showing the first eight; more decompositions exist.
