Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295071878, here are decompositions:

7 + 4295071871 = 4295071878
89 + 4295071789 = 4295071878
109 + 4295071769 = 4295071878
127 + 4295071751 = 4295071878
137 + 4295071741 = 4295071878
157 + 4295071721 = 4295071878
211 + 4295071667 = 4295071878
269 + 4295071609 = 4295071878

Showing the first eight; more decompositions exist.
