Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985278, here are decompositions:

11 + 4294985267 = 4294985278
41 + 4294985237 = 4294985278
179 + 4294985099 = 4294985278
251 + 4294985027 = 4294985278
431 + 4294984847 = 4294985278
797 + 4294984481 = 4294985278
911 + 4294984367 = 4294985278
929 + 4294984349 = 4294985278

Showing the first eight; more decompositions exist.
