Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499212, here are decompositions:

  • 73 + 2147499139 = 2147499212
  • 619 + 2147498593 = 2147499212
  • 631 + 2147498581 = 2147499212
  • 1033 + 2147498179 = 2147499212
  • 1291 + 2147497921 = 2147499212
  • 1549 + 2147497663 = 2147499212
  • 1723 + 2147497489 = 2147499212
  • 1753 + 2147497459 = 2147499212

Showing the first eight; more decompositions exist.
