Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528122, here are decompositions:

31 + 528091 = 528122
79 + 528043 = 528122
109 + 528013 = 528122
139 + 527983 = 528122
181 + 527941 = 528122
193 + 527929 = 528122
241 + 527881 = 528122
271 + 527851 = 528122

Showing the first eight; more decompositions exist.
