Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498318, here are decompositions:

  • 109 + 2147498209 = 2147498318
  • 139 + 2147498179 = 2147498318
  • 241 + 2147498077 = 2147498318
  • 379 + 2147497939 = 2147498318
  • 397 + 2147497921 = 2147498318
  • 547 + 2147497771 = 2147498318
  • 601 + 2147497717 = 2147498318
  • 619 + 2147497699 = 2147498318

Showing the first eight; more decompositions exist.
