Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543916, here are decompositions:

3 + 31543913 = 31543916
13 + 31543903 = 31543916
43 + 31543873 = 31543916
73 + 31543843 = 31543916
139 + 31543777 = 31543916
193 + 31543723 = 31543916
337 + 31543579 = 31543916
373 + 31543543 = 31543916

Showing the first eight; more decompositions exist.
