Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544016, here are decompositions:

5 + 31544011 = 31544016
19 + 31543997 = 31544016
29 + 31543987 = 31544016
37 + 31543979 = 31544016
89 + 31543927 = 31544016
103 + 31543913 = 31544016
109 + 31543907 = 31544016
113 + 31543903 = 31544016

Showing the first eight; more decompositions exist.
