Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631180, here are decompositions:

13 + 8631167 = 8631180
29 + 8631151 = 8631180
71 + 8631109 = 8631180
83 + 8631097 = 8631180
97 + 8631083 = 8631180
139 + 8631041 = 8631180
157 + 8631023 = 8631180
163 + 8631017 = 8631180

Showing the first eight; more decompositions exist.
