Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631342, here are decompositions:

11 + 8631331 = 8631342
23 + 8631319 = 8631342
59 + 8631283 = 8631342
73 + 8631269 = 8631342
113 + 8631229 = 8631342
149 + 8631193 = 8631342
151 + 8631191 = 8631342
191 + 8631151 = 8631342

Showing the first eight; more decompositions exist.
