Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606948, here are decompositions:

5 + 31606943 = 31606948
17 + 31606931 = 31606948
29 + 31606919 = 31606948
101 + 31606847 = 31606948
137 + 31606811 = 31606948
251 + 31606697 = 31606948
257 + 31606691 = 31606948
281 + 31606667 = 31606948

Showing the first eight; more decompositions exist.
