Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522122, here are decompositions:

43 + 522079 = 522122
61 + 522061 = 522122
193 + 521929 = 522122
199 + 521923 = 522122
241 + 521881 = 522122
313 + 521809 = 522122
331 + 521791 = 522122
373 + 521749 = 522122

Showing the first eight; more decompositions exist.
