Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590984, here are decompositions:

41 + 31590943 = 31590984
43 + 31590941 = 31590984
53 + 31590931 = 31590984
67 + 31590917 = 31590984
97 + 31590887 = 31590984
107 + 31590877 = 31590984
137 + 31590847 = 31590984
151 + 31590833 = 31590984

Showing the first eight; more decompositions exist.
