Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642118, here are decompositions:

7 + 8642111 = 8642118
11 + 8642107 = 8642118
19 + 8642099 = 8642118
41 + 8642077 = 8642118
59 + 8642059 = 8642118
61 + 8642057 = 8642118
127 + 8641991 = 8642118
131 + 8641987 = 8642118

Showing the first eight; more decompositions exist.
