Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566410, here are decompositions:

13 + 31566397 = 31566410
61 + 31566349 = 31566410
163 + 31566247 = 31566410
241 + 31566169 = 31566410
331 + 31566079 = 31566410
349 + 31566061 = 31566410
367 + 31566043 = 31566410
397 + 31566013 = 31566410

Showing the first eight; more decompositions exist.
