Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628330, here are decompositions:

37 + 8628293 = 8628330
59 + 8628271 = 8628330
97 + 8628233 = 8628330
127 + 8628203 = 8628330
149 + 8628181 = 8628330
157 + 8628173 = 8628330
173 + 8628157 = 8628330
181 + 8628149 = 8628330

Showing the first eight; more decompositions exist.
