Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020222, here are decompositions:

59 + 1020163 = 1020222
79 + 1020143 = 1020222
109 + 1020113 = 1020222
113 + 1020109 = 1020222
163 + 1020059 = 1020222
173 + 1020049 = 1020222
179 + 1020043 = 1020222
199 + 1020023 = 1020222

Showing the first eight; more decompositions exist.
