Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606338, here are decompositions:

7 + 31606331 = 31606338
19 + 31606319 = 31606338
41 + 31606297 = 31606338
59 + 31606279 = 31606338
61 + 31606277 = 31606338
151 + 31606187 = 31606338
157 + 31606181 = 31606338
241 + 31606097 = 31606338

Showing the first eight; more decompositions exist.
