Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981222, here are decompositions:

13 + 981209 = 981222
23 + 981199 = 981222
71 + 981151 = 981222
83 + 981139 = 981222
89 + 981133 = 981222
131 + 981091 = 981222
149 + 981073 = 981222
173 + 981049 = 981222

Showing the first eight; more decompositions exist.
