Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566302, here are decompositions:

3 + 31566299 = 31566302
13 + 31566289 = 31566302
151 + 31566151 = 31566302
223 + 31566079 = 31566302
241 + 31566061 = 31566302
283 + 31566019 = 31566302
331 + 31565971 = 31566302
349 + 31565953 = 31566302

Showing the first eight; more decompositions exist.
