Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631290, here are decompositions:

7 + 8631283 = 8631290
13 + 8631277 = 8631290
43 + 8631247 = 8631290
61 + 8631229 = 8631290
97 + 8631193 = 8631290
139 + 8631151 = 8631290
181 + 8631109 = 8631290
193 + 8631097 = 8631290

Showing the first eight; more decompositions exist.
