Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967940, here are decompositions:

73 + 4294967867 = 4294967940
79 + 4294967861 = 4294967940
83 + 4294967857 = 4294967940
149 + 4294967791 = 4294967940
157 + 4294967783 = 4294967940
181 + 4294967759 = 4294967940
239 + 4294967701 = 4294967940
313 + 4294967627 = 4294967940

Showing the first eight; more decompositions exist.
