Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997422, here are decompositions:

31 + 997391 = 997422
43 + 997379 = 997422
53 + 997369 = 997422
79 + 997343 = 997422
89 + 997333 = 997422
103 + 997319 = 997422
113 + 997309 = 997422
149 + 997273 = 997422

Showing the first eight; more decompositions exist.
