Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522188, here are decompositions:

31 + 522157 = 522188
61 + 522127 = 522188
109 + 522079 = 522188
127 + 522061 = 522188
151 + 522037 = 522188
307 + 521881 = 522188
379 + 521809 = 522188
397 + 521791 = 522188

Showing the first eight; more decompositions exist.
