Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522212, here are decompositions:

13 + 522199 = 522212
139 + 522073 = 522212
151 + 522061 = 522212
283 + 521929 = 522212
331 + 521881 = 522212
421 + 521791 = 522212
463 + 521749 = 522212
541 + 521671 = 522212

Showing the first eight; more decompositions exist.
