Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630222, here are decompositions:

31 + 8630191 = 8630222
43 + 8630179 = 8630222
103 + 8630119 = 8630222
109 + 8630113 = 8630222
151 + 8630071 = 8630222
193 + 8630029 = 8630222
241 + 8629981 = 8630222
313 + 8629909 = 8630222

Showing the first eight; more decompositions exist.
