Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500144, here are decompositions:

  • 5 + 2147500139 = 2147500144
  • 17 + 2147500127 = 2147500144
  • 137 + 2147500007 = 2147500144
  • 191 + 2147499953 = 2147500144
  • 227 + 2147499917 = 2147500144
  • 281 + 2147499863 = 2147500144
  • 683 + 2147499461 = 2147500144
  • 743 + 2147499401 = 2147500144

Showing the first eight; more decompositions exist.
