Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642116, here are decompositions:

5 + 8642111 = 8642116
17 + 8642099 = 8642116
53 + 8642063 = 8642116
59 + 8642057 = 8642116
83 + 8642033 = 8642116
89 + 8642027 = 8642116
113 + 8642003 = 8642116
167 + 8641949 = 8642116

Showing the first eight; more decompositions exist.
