Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478610, here are decompositions:

  • 29 + 2147478581 = 2147478610
  • 41 + 2147478569 = 2147478610
  • 47 + 2147478563 = 2147478610
  • 89 + 2147478521 = 2147478610
  • 107 + 2147478503 = 2147478610
  • 113 + 2147478497 = 2147478610
  • 149 + 2147478461 = 2147478610
  • 311 + 2147478299 = 2147478610

Showing the first eight; more decompositions exist.
