Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399804, here are decompositions:

  • 37 + 2147399767 = 2147399804
  • 73 + 2147399731 = 2147399804
  • 103 + 2147399701 = 2147399804
  • 211 + 2147399593 = 2147399804
  • 223 + 2147399581 = 2147399804
  • 271 + 2147399533 = 2147399804
  • 283 + 2147399521 = 2147399804
  • 313 + 2147399491 = 2147399804

Showing the first eight; more decompositions exist.
