Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499238, here are decompositions:

  • 167 + 2147499071 = 2147499238
  • 179 + 2147499059 = 2147499238
  • 239 + 2147498999 = 2147499238
  • 281 + 2147498957 = 2147499238
  • 509 + 2147498729 = 2147499238
  • 719 + 2147498519 = 2147499238
  • 839 + 2147498399 = 2147499238
  • 1049 + 2147498189 = 2147499238

Showing the first eight; more decompositions exist.
