Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021238, here are decompositions:

5 + 4295021233 = 4295021238
17 + 4295021221 = 4295021238
29 + 4295021209 = 4295021238
31 + 4295021207 = 4295021238
41 + 4295021197 = 4295021238
71 + 4295021167 = 4295021238
181 + 4295021057 = 4295021238
191 + 4295021047 = 4295021238

Showing the first eight; more decompositions exist.
