Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988868, here are decompositions:

7 + 4294988861 = 4294988868
19 + 4294988849 = 4294988868
67 + 4294988801 = 4294988868
179 + 4294988689 = 4294988868
227 + 4294988641 = 4294988868
277 + 4294988591 = 4294988868
307 + 4294988561 = 4294988868
311 + 4294988557 = 4294988868

Showing the first eight; more decompositions exist.
