Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543914, here are decompositions:

7 + 31543907 = 31543914
11 + 31543903 = 31543914
37 + 31543877 = 31543914
41 + 31543873 = 31543914
43 + 31543871 = 31543914
67 + 31543847 = 31543914
71 + 31543843 = 31543914
97 + 31543817 = 31543914

Showing the first eight; more decompositions exist.
