Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522146, here are decompositions:

19 + 522127 = 522146
67 + 522079 = 522146
73 + 522073 = 522146
109 + 522037 = 522146
223 + 521923 = 522146
277 + 521869 = 522146
337 + 521809 = 522146
379 + 521767 = 522146

Showing the first eight; more decompositions exist.
