Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546916, here are decompositions:

3 + 31546913 = 31546916
7 + 31546909 = 31546916
73 + 31546843 = 31546916
103 + 31546813 = 31546916
109 + 31546807 = 31546916
127 + 31546789 = 31546916
157 + 31546759 = 31546916
199 + 31546717 = 31546916

Showing the first eight; more decompositions exist.
