Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002122, here are decompositions:

13 + 1002109 = 1002122
31 + 1002091 = 1002122
61 + 1002061 = 1002122
73 + 1002049 = 1002122
139 + 1001983 = 1002122
181 + 1001941 = 1002122
211 + 1001911 = 1002122
283 + 1001839 = 1002122

Showing the first eight; more decompositions exist.
