Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522198, here are decompositions:

7 + 522191 = 522198
31 + 522167 = 522198
37 + 522161 = 522198
41 + 522157 = 522198
71 + 522127 = 522198
137 + 522061 = 522198
139 + 522059 = 522198
151 + 522047 = 522198

Showing the first eight; more decompositions exist.
