Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606116, here are decompositions:

19 + 31606097 = 31606116
29 + 31606087 = 31606116
37 + 31606079 = 31606116
67 + 31606049 = 31606116
163 + 31605953 = 31606116
239 + 31605877 = 31606116
293 + 31605823 = 31606116
307 + 31605809 = 31606116

Showing the first eight; more decompositions exist.
