Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566064, here are decompositions:

3 + 31566061 = 31566064
71 + 31565993 = 31566064
83 + 31565981 = 31566064
293 + 31565771 = 31566064
401 + 31565663 = 31566064
461 + 31565603 = 31566064
503 + 31565561 = 31566064
641 + 31565423 = 31566064

Showing the first eight; more decompositions exist.
