Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606284, here are decompositions:

5 + 31606279 = 31606284
7 + 31606277 = 31606284
23 + 31606261 = 31606284
97 + 31606187 = 31606284
103 + 31606181 = 31606284
197 + 31606087 = 31606284
223 + 31606061 = 31606284
233 + 31606051 = 31606284

Showing the first eight; more decompositions exist.
