Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522158, here are decompositions:

31 + 522127 = 522158
79 + 522079 = 522158
97 + 522061 = 522158
229 + 521929 = 522158
271 + 521887 = 522158
277 + 521881 = 522158
349 + 521809 = 522158
367 + 521791 = 522158

Showing the first eight; more decompositions exist.
