Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021920, here are decompositions:

17 + 4295021903 = 4295021920
47 + 4295021873 = 4295021920
53 + 4295021867 = 4295021920
107 + 4295021813 = 4295021920
197 + 4295021723 = 4295021920
239 + 4295021681 = 4295021920
257 + 4295021663 = 4295021920
281 + 4295021639 = 4295021920

Showing the first eight; more decompositions exist.
