Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498618, here are decompositions:

  • 37 + 2147498581 = 2147498618
  • 271 + 2147498347 = 2147498618
  • 277 + 2147498341 = 2147498618
  • 409 + 2147498209 = 2147498618
  • 439 + 2147498179 = 2147498618
  • 541 + 2147498077 = 2147498618
  • 919 + 2147497699 = 2147498618
  • 1129 + 2147497489 = 2147498618

Showing the first eight; more decompositions exist.
