Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590944, here are decompositions:

3 + 31590941 = 31590944
13 + 31590931 = 31590944
37 + 31590907 = 31590944
67 + 31590877 = 31590944
97 + 31590847 = 31590944
103 + 31590841 = 31590944
181 + 31590763 = 31590944
211 + 31590733 = 31590944

Showing the first eight; more decompositions exist.
