Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542834, here are decompositions:

5 + 31542829 = 31542834
7 + 31542827 = 31542834
23 + 31542811 = 31542834
47 + 31542787 = 31542834
67 + 31542767 = 31542834
107 + 31542727 = 31542834
131 + 31542703 = 31542834
137 + 31542697 = 31542834

Showing the first eight; more decompositions exist.
