Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566382, here are decompositions:

5 + 31566377 = 31566382
53 + 31566329 = 31566382
83 + 31566299 = 31566382
131 + 31566251 = 31566382
191 + 31566191 = 31566382
251 + 31566131 = 31566382
389 + 31565993 = 31566382
401 + 31565981 = 31566382

Showing the first eight; more decompositions exist.
