Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628136, here are decompositions:

5 + 8628131 = 8628136
29 + 8628107 = 8628136
59 + 8628077 = 8628136
149 + 8627987 = 8628136
197 + 8627939 = 8628136
227 + 8627909 = 8628136
233 + 8627903 = 8628136
239 + 8627897 = 8628136

Showing the first eight; more decompositions exist.
