Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628156, here are decompositions:

7 + 8628149 = 8628156
59 + 8628097 = 8628156
79 + 8628077 = 8628156
107 + 8628049 = 8628156
137 + 8628019 = 8628156
139 + 8628017 = 8628156
149 + 8628007 = 8628156
179 + 8627977 = 8628156

Showing the first eight; more decompositions exist.
