Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573008, here are decompositions:

29 + 31572979 = 31573008
37 + 31572971 = 31573008
59 + 31572949 = 31573008
67 + 31572941 = 31573008
107 + 31572901 = 31573008
127 + 31572881 = 31573008
139 + 31572869 = 31573008
167 + 31572841 = 31573008

Showing the first eight; more decompositions exist.
