Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628412, here are decompositions:

5 + 8628407 = 8628412
29 + 8628383 = 8628412
53 + 8628359 = 8628412
59 + 8628353 = 8628412
179 + 8628233 = 8628412
239 + 8628173 = 8628412
251 + 8628161 = 8628412
263 + 8628149 = 8628412

Showing the first eight; more decompositions exist.
