Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630042, here are decompositions:

13 + 8630029 = 8630042
61 + 8629981 = 8630042
79 + 8629963 = 8630042
151 + 8629891 = 8630042
229 + 8629813 = 8630042
271 + 8629771 = 8630042
331 + 8629711 = 8630042
601 + 8629441 = 8630042

Showing the first eight; more decompositions exist.
