Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492068, here are decompositions:

7 + 31492061 = 31492068
17 + 31492051 = 31492068
37 + 31492031 = 31492068
79 + 31491989 = 31492068
109 + 31491959 = 31492068
151 + 31491917 = 31492068
227 + 31491841 = 31492068
277 + 31491791 = 31492068

Showing the first eight; more decompositions exist.
