Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497666, here are decompositions:

3 + 2147497663 = 2147497666
5 + 2147497661 = 2147497666
107 + 2147497559 = 2147497666
173 + 2147497493 = 2147497666
263 + 2147497403 = 2147497666
317 + 2147497349 = 2147497666
647 + 2147497019 = 2147497666
827 + 2147496839 = 2147497666

Showing the first eight; more decompositions exist.
