Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020122, here are decompositions:

13 + 1020109 = 1020122
43 + 1020079 = 1020122
73 + 1020049 = 1020122
79 + 1020043 = 1020122
109 + 1020013 = 1020122
151 + 1019971 = 1020122
223 + 1019899 = 1020122
283 + 1019839 = 1020122

Showing the first eight; more decompositions exist.
