Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622180, here are decompositions:

43 + 8622137 = 8622180
53 + 8622127 = 8622180
67 + 8622113 = 8622180
109 + 8622071 = 8622180
139 + 8622041 = 8622180
157 + 8622023 = 8622180
163 + 8622017 = 8622180
173 + 8622007 = 8622180

Showing the first eight; more decompositions exist.
