Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021820, here are decompositions:

7 + 4295021813 = 4295021820
53 + 4295021767 = 4295021820
71 + 4295021749 = 4295021820
83 + 4295021737 = 4295021820
97 + 4295021723 = 4295021820
139 + 4295021681 = 4295021820
149 + 4295021671 = 4295021820
157 + 4295021663 = 4295021820

Showing the first eight; more decompositions exist.
