Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522168, here are decompositions:

7 + 522161 = 522168
11 + 522157 = 522168
41 + 522127 = 522168
89 + 522079 = 522168
107 + 522061 = 522168
109 + 522059 = 522168
131 + 522037 = 522168
151 + 522017 = 522168

Showing the first eight; more decompositions exist.
