Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628146, here are decompositions:

97 + 8628049 = 8628146
127 + 8628019 = 8628146
139 + 8628007 = 8628146
193 + 8627953 = 8628146
199 + 8627947 = 8628146
313 + 8627833 = 8628146
337 + 8627809 = 8628146
433 + 8627713 = 8628146

Showing the first eight; more decompositions exist.
