Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478850, here are decompositions:

  • 29 + 2147478821 = 2147478850
  • 59 + 2147478791 = 2147478850
  • 131 + 2147478719 = 2147478850
  • 149 + 2147478701 = 2147478850
  • 191 + 2147478659 = 2147478850
  • 197 + 2147478653 = 2147478850
  • 239 + 2147478611 = 2147478850
  • 269 + 2147478581 = 2147478850

Showing the first eight; more decompositions exist.
