Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628032, here are decompositions:

13 + 8628019 = 8628032
79 + 8627953 = 8628032
139 + 8627893 = 8628032
181 + 8627851 = 8628032
199 + 8627833 = 8628032
223 + 8627809 = 8628032
331 + 8627701 = 8628032
421 + 8627611 = 8628032

Showing the first eight; more decompositions exist.
