Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467238, here are decompositions:

  • 19 + 2147467219 = 2147467238
  • 181 + 2147467057 = 2147467238
  • 229 + 2147467009 = 2147467238
  • 307 + 2147466931 = 2147467238
  • 691 + 2147466547 = 2147467238
  • 751 + 2147466487 = 2147467238
  • 811 + 2147466427 = 2147467238
  • 919 + 2147466319 = 2147467238

Showing the first eight; more decompositions exist.
