Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506954, here are decompositions:

5 + 31506949 = 31506954
23 + 31506931 = 31506954
43 + 31506911 = 31506954
47 + 31506907 = 31506954
67 + 31506887 = 31506954
113 + 31506841 = 31506954
131 + 31506823 = 31506954
163 + 31506791 = 31506954

Showing the first eight; more decompositions exist.
