Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688210, here are decompositions:

7 + 8688203 = 8688210
43 + 8688167 = 8688210
53 + 8688157 = 8688210
67 + 8688143 = 8688210
101 + 8688109 = 8688210
109 + 8688101 = 8688210
127 + 8688083 = 8688210
151 + 8688059 = 8688210

Showing the first eight; more decompositions exist.
