Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628012, here are decompositions:

5 + 8628007 = 8628012
59 + 8627953 = 8628012
73 + 8627939 = 8628012
101 + 8627911 = 8628012
103 + 8627909 = 8628012
109 + 8627903 = 8628012
179 + 8627833 = 8628012
199 + 8627813 = 8628012

Showing the first eight; more decompositions exist.
