Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516834, here are decompositions:

23 + 31516811 = 31516834
47 + 31516787 = 31516834
53 + 31516781 = 31516834
131 + 31516703 = 31516834
137 + 31516697 = 31516834
263 + 31516571 = 31516834
311 + 31516523 = 31516834
593 + 31516241 = 31516834

Showing the first eight; more decompositions exist.
