Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547012, here are decompositions:

31 + 31546981 = 31547012
43 + 31546969 = 31547012
103 + 31546909 = 31547012
151 + 31546861 = 31547012
181 + 31546831 = 31547012
199 + 31546813 = 31547012
223 + 31546789 = 31547012
271 + 31546741 = 31547012

Showing the first eight; more decompositions exist.
