Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499194, here are decompositions:

  • 103 + 2147499091 = 2147499194
  • 157 + 2147499037 = 2147499194
  • 241 + 2147498953 = 2147499194
  • 277 + 2147498917 = 2147499194
  • 283 + 2147498911 = 2147499194
  • 367 + 2147498827 = 2147499194
  • 397 + 2147498797 = 2147499194
  • 457 + 2147498737 = 2147499194

Showing the first eight; more decompositions exist.
