Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590954, here are decompositions:

11 + 31590943 = 31590954
13 + 31590941 = 31590954
23 + 31590931 = 31590954
37 + 31590917 = 31590954
47 + 31590907 = 31590954
61 + 31590893 = 31590954
67 + 31590887 = 31590954
107 + 31590847 = 31590954

Showing the first eight; more decompositions exist.
