Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478828, here are decompositions:

  • 7 + 2147478821 = 2147478828
  • 37 + 2147478791 = 2147478828
  • 97 + 2147478731 = 2147478828
  • 101 + 2147478727 = 2147478828
  • 107 + 2147478721 = 2147478828
  • 109 + 2147478719 = 2147478828
  • 127 + 2147478701 = 2147478828
  • 167 + 2147478661 = 2147478828

Showing the first eight; more decompositions exist.
