Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622128, here are decompositions:

127 + 8622001 = 8622128
139 + 8621989 = 8622128
157 + 8621971 = 8622128
181 + 8621947 = 8622128
271 + 8621857 = 8622128
331 + 8621797 = 8622128
349 + 8621779 = 8622128
379 + 8621749 = 8622128

Showing the first eight; more decompositions exist.
