Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999728, here are decompositions:

7 + 4294999721 = 4294999728
11 + 4294999717 = 4294999728
29 + 4294999699 = 4294999728
179 + 4294999549 = 4294999728
181 + 4294999547 = 4294999728
191 + 4294999537 = 4294999728
251 + 4294999477 = 4294999728
307 + 4294999421 = 4294999728

Showing the first eight; more decompositions exist.
