Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498144, here are decompositions:

  • 3 + 2147498141 = 2147498144
  • 67 + 2147498077 = 2147498144
  • 223 + 2147497921 = 2147498144
  • 373 + 2147497771 = 2147498144
  • 733 + 2147497411 = 2147498144
  • 751 + 2147497393 = 2147498144
  • 823 + 2147497321 = 2147498144
  • 907 + 2147497237 = 2147498144

Showing the first eight; more decompositions exist.
