Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606302, here are decompositions:

5 + 31606297 = 31606302
19 + 31606283 = 31606302
23 + 31606279 = 31606302
41 + 31606261 = 31606302
223 + 31606079 = 31606302
241 + 31606061 = 31606302
251 + 31606051 = 31606302
331 + 31605971 = 31606302

Showing the first eight; more decompositions exist.
