Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987998, here are decompositions:

47 + 4294987951 = 4294987998
79 + 4294987919 = 4294987998
109 + 4294987889 = 4294987998
139 + 4294987859 = 4294987998
149 + 4294987849 = 4294987998
151 + 4294987847 = 4294987998
199 + 4294987799 = 4294987998
227 + 4294987771 = 4294987998

Showing the first eight; more decompositions exist.
