Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546844, here are decompositions:

13 + 31546831 = 31546844
31 + 31546813 = 31546844
37 + 31546807 = 31546844
103 + 31546741 = 31546844
127 + 31546717 = 31546844
181 + 31546663 = 31546844
211 + 31546633 = 31546844
223 + 31546621 = 31546844

Showing the first eight; more decompositions exist.
