Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606954, here are decompositions:

3 + 31606951 = 31606954
11 + 31606943 = 31606954
23 + 31606931 = 31606954
107 + 31606847 = 31606954
227 + 31606727 = 31606954
251 + 31606703 = 31606954
257 + 31606697 = 31606954
263 + 31606691 = 31606954

Showing the first eight; more decompositions exist.
