Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642154, here are decompositions:

7 + 8642147 = 8642154
13 + 8642141 = 8642154
43 + 8642111 = 8642154
47 + 8642107 = 8642154
97 + 8642057 = 8642154
127 + 8642027 = 8642154
151 + 8642003 = 8642154
163 + 8641991 = 8642154

Showing the first eight; more decompositions exist.
