Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999980, here are decompositions:

23 + 4294999957 = 4294999980
31 + 4294999949 = 4294999980
41 + 4294999939 = 4294999980
163 + 4294999817 = 4294999980
211 + 4294999769 = 4294999980
239 + 4294999741 = 4294999980
263 + 4294999717 = 4294999980
281 + 4294999699 = 4294999980

Showing the first eight; more decompositions exist.
