Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497918, here are decompositions:

  • 11 + 2147497907 = 2147497918
  • 17 + 2147497901 = 2147497918
  • 29 + 2147497889 = 2147497918
  • 149 + 2147497769 = 2147497918
  • 227 + 2147497691 = 2147497918
  • 257 + 2147497661 = 2147497918
  • 347 + 2147497571 = 2147497918
  • 359 + 2147497559 = 2147497918

Showing the first eight; more decompositions exist.
