Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589940, here are decompositions:

17 + 31589923 = 31589940
71 + 31589869 = 31589940
73 + 31589867 = 31589940
79 + 31589861 = 31589940
97 + 31589843 = 31589940
113 + 31589827 = 31589940
163 + 31589777 = 31589940
167 + 31589773 = 31589940

Showing the first eight; more decompositions exist.
