Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522278, here are decompositions:

19 + 522259 = 522278
67 + 522211 = 522278
79 + 522199 = 522278
151 + 522127 = 522278
199 + 522079 = 522278
241 + 522037 = 522278
349 + 521929 = 522278
397 + 521881 = 522278

Showing the first eight; more decompositions exist.
