Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606984, here are decompositions:

5 + 31606979 = 31606984
11 + 31606973 = 31606984
41 + 31606943 = 31606984
53 + 31606931 = 31606984
137 + 31606847 = 31606984
173 + 31606811 = 31606984
257 + 31606727 = 31606984
281 + 31606703 = 31606984

Showing the first eight; more decompositions exist.
