Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461996, here are decompositions:

17 + 31461979 = 31461996
19 + 31461977 = 31461996
47 + 31461949 = 31461996
53 + 31461943 = 31461996
73 + 31461923 = 31461996
103 + 31461893 = 31461996
109 + 31461887 = 31461996
173 + 31461823 = 31461996

Showing the first eight; more decompositions exist.
