Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606998, here are decompositions:

19 + 31606979 = 31606998
41 + 31606957 = 31606998
47 + 31606951 = 31606998
67 + 31606931 = 31606998
79 + 31606919 = 31606998
151 + 31606847 = 31606998
257 + 31606741 = 31606998
271 + 31606727 = 31606998

Showing the first eight; more decompositions exist.
