Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628162, here are decompositions:

5 + 8628157 = 8628162
13 + 8628149 = 8628162
31 + 8628131 = 8628162
41 + 8628121 = 8628162
113 + 8628049 = 8628162
131 + 8628031 = 8628162
223 + 8627939 = 8628162
251 + 8627911 = 8628162

Showing the first eight; more decompositions exist.
