Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021990, here are decompositions:

13 + 4295021977 = 4295021990
67 + 4295021923 = 4295021990
139 + 4295021851 = 4295021990
223 + 4295021767 = 4295021990
241 + 4295021749 = 4295021990
331 + 4295021659 = 4295021990
349 + 4295021641 = 4295021990
421 + 4295021569 = 4295021990

Showing the first eight; more decompositions exist.
