Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499282, here are decompositions:

  • 29 + 2147499253 = 2147499282
  • 41 + 2147499241 = 2147499282
  • 163 + 2147499119 = 2147499282
  • 191 + 2147499091 = 2147499282
  • 211 + 2147499071 = 2147499282
  • 223 + 2147499059 = 2147499282
  • 283 + 2147498999 = 2147499282
  • 389 + 2147498893 = 2147499282

Showing the first eight; more decompositions exist.
