Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021780, here are decompositions:

13 + 4295021767 = 4295021780
31 + 4295021749 = 4295021780
43 + 4295021737 = 4295021780
109 + 4295021671 = 4295021780
139 + 4295021641 = 4295021780
151 + 4295021629 = 4295021780
211 + 4295021569 = 4295021780
229 + 4295021551 = 4295021780

Showing the first eight; more decompositions exist.
