Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628158, here are decompositions:

37 + 8628121 = 8628158
61 + 8628097 = 8628158
109 + 8628049 = 8628158
127 + 8628031 = 8628158
139 + 8628019 = 8628158
151 + 8628007 = 8628158
181 + 8627977 = 8628158
211 + 8627947 = 8628158

Showing the first eight; more decompositions exist.
