Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546940, here are decompositions:

3 + 31546937 = 31546940
31 + 31546909 = 31546940
79 + 31546861 = 31546940
97 + 31546843 = 31546940
109 + 31546831 = 31546940
127 + 31546813 = 31546940
151 + 31546789 = 31546940
181 + 31546759 = 31546940

Showing the first eight; more decompositions exist.
