Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450164, here are decompositions:

23 + 31450141 = 31450164
47 + 31450117 = 31450164
61 + 31450103 = 31450164
71 + 31450093 = 31450164
103 + 31450061 = 31450164
107 + 31450057 = 31450164
131 + 31450033 = 31450164
173 + 31449991 = 31450164

Showing the first eight; more decompositions exist.
