Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499078, here are decompositions:

  • 7 + 2147499071 = 2147499078
  • 19 + 2147499059 = 2147499078
  • 41 + 2147499037 = 2147499078
  • 61 + 2147499017 = 2147499078
  • 79 + 2147498999 = 2147499078
  • 167 + 2147498911 = 2147499078
  • 251 + 2147498827 = 2147499078
  • 281 + 2147498797 = 2147499078

Showing the first eight; more decompositions exist.
