Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85122, here are decompositions:

13 + 85109 = 85122
19 + 85103 = 85122
29 + 85093 = 85122
31 + 85091 = 85122
41 + 85081 = 85122
61 + 85061 = 85122
73 + 85049 = 85122
101 + 85021 = 85122

Showing the first eight; more decompositions exist.
