Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645330, here are decompositions:

3 + 8645327 = 8645330
37 + 8645293 = 8645330
61 + 8645269 = 8645330
73 + 8645257 = 8645330
151 + 8645179 = 8645330
277 + 8645053 = 8645330
283 + 8645047 = 8645330
307 + 8645023 = 8645330

Showing the first eight; more decompositions exist.
