Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566008, here are decompositions:

7 + 31566001 = 31566008
37 + 31565971 = 31566008
79 + 31565929 = 31566008
139 + 31565869 = 31566008
157 + 31565851 = 31566008
307 + 31565701 = 31566008
337 + 31565671 = 31566008
547 + 31565461 = 31566008

Showing the first eight; more decompositions exist.
