Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511422, here are decompositions:

5 + 511417 = 511422
13 + 511409 = 511422
31 + 511391 = 511422
61 + 511361 = 511422
71 + 511351 = 511422
89 + 511333 = 511422
179 + 511243 = 511422
199 + 511223 = 511422

Showing the first eight; more decompositions exist.
