Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543716, here are decompositions:

5 + 31543711 = 31543716
19 + 31543697 = 31543716
47 + 31543669 = 31543716
73 + 31543643 = 31543716
137 + 31543579 = 31543716
173 + 31543543 = 31543716
227 + 31543489 = 31543716
263 + 31543453 = 31543716

Showing the first eight; more decompositions exist.
