Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501818, here are decompositions:

  • 41 + 2147501777 = 2147501818
  • 101 + 2147501717 = 2147501818
  • 149 + 2147501669 = 2147501818
  • 191 + 2147501627 = 2147501818
  • 569 + 2147501249 = 2147501818
  • 641 + 2147501177 = 2147501818
  • 809 + 2147501009 = 2147501818
  • 881 + 2147500937 = 2147501818

Showing the first eight; more decompositions exist.
