Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499220, here are decompositions:

  • 3 + 2147499217 = 2147499220
  • 59 + 2147499161 = 2147499220
  • 101 + 2147499119 = 2147499220
  • 149 + 2147499071 = 2147499220
  • 257 + 2147498963 = 2147499220
  • 263 + 2147498957 = 2147499220
  • 389 + 2147498831 = 2147499220
  • 479 + 2147498741 = 2147499220

Showing the first eight; more decompositions exist.
