Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499290, here are decompositions:

  • 7 + 2147499283 = 2147499290
  • 37 + 2147499253 = 2147499290
  • 73 + 2147499217 = 2147499290
  • 151 + 2147499139 = 2147499290
  • 199 + 2147499091 = 2147499290
  • 337 + 2147498953 = 2147499290
  • 373 + 2147498917 = 2147499290
  • 379 + 2147498911 = 2147499290

Showing the first eight; more decompositions exist.
