Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516206, here are decompositions:

5 + 31516201 = 31516206
17 + 31516189 = 31516206
23 + 31516183 = 31516206
47 + 31516159 = 31516206
53 + 31516153 = 31516206
67 + 31516139 = 31516206
83 + 31516123 = 31516206
97 + 31516109 = 31516206

Showing the first eight; more decompositions exist.
