Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987992, here are decompositions:

41 + 4294987951 = 4294987992
73 + 4294987919 = 4294987992
89 + 4294987903 = 4294987992
103 + 4294987889 = 4294987992
193 + 4294987799 = 4294987992
223 + 4294987769 = 4294987992
241 + 4294987751 = 4294987992
311 + 4294987681 = 4294987992

Showing the first eight; more decompositions exist.
