Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498402, here are decompositions:

  • 3 + 2147498399 = 2147498402
  • 61 + 2147498341 = 2147498402
  • 193 + 2147498209 = 2147498402
  • 223 + 2147498179 = 2147498402
  • 463 + 2147497939 = 2147498402
  • 631 + 2147497771 = 2147498402
  • 739 + 2147497663 = 2147498402
  • 991 + 2147497411 = 2147498402

Showing the first eight; more decompositions exist.
