Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631240, here are decompositions:

11 + 8631229 = 8631240
41 + 8631199 = 8631240
47 + 8631193 = 8631240
73 + 8631167 = 8631240
89 + 8631151 = 8631240
131 + 8631109 = 8631240
157 + 8631083 = 8631240
199 + 8631041 = 8631240

Showing the first eight; more decompositions exist.
