Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597122, here are decompositions:

23 + 31597099 = 31597122
41 + 31597081 = 31597122
71 + 31597051 = 31597122
79 + 31597043 = 31597122
131 + 31596991 = 31597122
173 + 31596949 = 31597122
199 + 31596923 = 31597122
223 + 31596899 = 31597122

Showing the first eight; more decompositions exist.
