Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630142, here are decompositions:

23 + 8630119 = 8630142
29 + 8630113 = 8630142
71 + 8630071 = 8630142
113 + 8630029 = 8630142
139 + 8630003 = 8630142
179 + 8629963 = 8630142
181 + 8629961 = 8630142
193 + 8629949 = 8630142

Showing the first eight; more decompositions exist.
