Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987900, here are decompositions:

11 + 4294987889 = 4294987900
41 + 4294987859 = 4294987900
53 + 4294987847 = 4294987900
101 + 4294987799 = 4294987900
131 + 4294987769 = 4294987900
149 + 4294987751 = 4294987900
197 + 4294987703 = 4294987900
293 + 4294987607 = 4294987900

Showing the first eight; more decompositions exist.
