Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498390, here are decompositions:

  • 3 + 2147498387 = 2147498390
  • 43 + 2147498347 = 2147498390
  • 181 + 2147498209 = 2147498390
  • 211 + 2147498179 = 2147498390
  • 313 + 2147498077 = 2147498390
  • 619 + 2147497771 = 2147498390
  • 673 + 2147497717 = 2147498390
  • 691 + 2147497699 = 2147498390

Showing the first eight; more decompositions exist.
