Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546980, here are decompositions:

11 + 31546969 = 31546980
43 + 31546937 = 31546980
67 + 31546913 = 31546980
71 + 31546909 = 31546980
89 + 31546891 = 31546980
137 + 31546843 = 31546980
149 + 31546831 = 31546980
163 + 31546817 = 31546980

Showing the first eight; more decompositions exist.
