Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629290, here are decompositions:

11 + 8629279 = 8629290
97 + 8629193 = 8629290
149 + 8629141 = 8629290
151 + 8629139 = 8629290
167 + 8629123 = 8629290
181 + 8629109 = 8629290
211 + 8629079 = 8629290
227 + 8629063 = 8629290

Showing the first eight; more decompositions exist.
