Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630078, here are decompositions:

7 + 8630071 = 8630078
97 + 8629981 = 8630078
151 + 8629927 = 8630078
211 + 8629867 = 8630078
307 + 8629771 = 8630078
367 + 8629711 = 8630078
397 + 8629681 = 8630078
571 + 8629507 = 8630078

Showing the first eight; more decompositions exist.
