Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981422, here are decompositions:

3 + 981419 = 981422
31 + 981391 = 981422
103 + 981319 = 981422
139 + 981283 = 981422
151 + 981271 = 981422
181 + 981241 = 981422
223 + 981199 = 981422
271 + 981151 = 981422

Showing the first eight; more decompositions exist.
