Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586016, here are decompositions:

13 + 31586003 = 31586016
19 + 31585997 = 31586016
37 + 31585979 = 31586016
43 + 31585973 = 31586016
53 + 31585963 = 31586016
79 + 31585937 = 31586016
113 + 31585903 = 31586016
127 + 31585889 = 31586016

Showing the first eight; more decompositions exist.
