Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613168, here are decompositions:

7 + 8613161 = 8613168
19 + 8613149 = 8613168
41 + 8613127 = 8613168
61 + 8613107 = 8613168
79 + 8613089 = 8613168
127 + 8613041 = 8613168
149 + 8613019 = 8613168
167 + 8613001 = 8613168

Showing the first eight; more decompositions exist.
