Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987908, here are decompositions:

5 + 4294987903 = 4294987908
19 + 4294987889 = 4294987908
59 + 4294987849 = 4294987908
61 + 4294987847 = 4294987908
109 + 4294987799 = 4294987908
137 + 4294987771 = 4294987908
139 + 4294987769 = 4294987908
151 + 4294987757 = 4294987908

Showing the first eight; more decompositions exist.
