Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147445062, here are decompositions:

  • 211 + 2147444851 = 2147445062
  • 229 + 2147444833 = 2147445062
  • 241 + 2147444821 = 2147445062
  • 271 + 2147444791 = 2147445062
  • 349 + 2147444713 = 2147445062
  • 673 + 2147444389 = 2147445062
  • 769 + 2147444293 = 2147445062
  • 811 + 2147444251 = 2147445062

Showing the first eight; more decompositions exist.
