Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631210, here are decompositions:

11 + 8631199 = 8631210
17 + 8631193 = 8631210
19 + 8631191 = 8631210
43 + 8631167 = 8631210
59 + 8631151 = 8631210
101 + 8631109 = 8631210
113 + 8631097 = 8631210
127 + 8631083 = 8631210

Showing the first eight; more decompositions exist.
