Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590040, here are decompositions:

3 + 31590037 = 31590040
29 + 31590011 = 31590040
59 + 31589981 = 31590040
149 + 31589891 = 31590040
173 + 31589867 = 31590040
179 + 31589861 = 31590040
197 + 31589843 = 31590040
263 + 31589777 = 31590040

Showing the first eight; more decompositions exist.
