Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642214, here are decompositions:

17 + 8642197 = 8642214
41 + 8642173 = 8642214
67 + 8642147 = 8642214
73 + 8642141 = 8642214
103 + 8642111 = 8642214
107 + 8642107 = 8642214
137 + 8642077 = 8642214
151 + 8642063 = 8642214

Showing the first eight; more decompositions exist.
