Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978788, here are decompositions:

7 + 4294978781 = 4294978788
11 + 4294978777 = 4294978788
31 + 4294978757 = 4294978788
59 + 4294978729 = 4294978788
109 + 4294978679 = 4294978788
127 + 4294978661 = 4294978788
197 + 4294978591 = 4294978788
229 + 4294978559 = 4294978788

Showing the first eight; more decompositions exist.
