Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628274, here are decompositions:

3 + 8628271 = 8628274
41 + 8628233 = 8628274
71 + 8628203 = 8628274
101 + 8628173 = 8628274
113 + 8628161 = 8628274
167 + 8628107 = 8628274
197 + 8628077 = 8628274
257 + 8628017 = 8628274

Showing the first eight; more decompositions exist.
