Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543896, here are decompositions:

19 + 31543877 = 31543896
23 + 31543873 = 31543896
37 + 31543859 = 31543896
53 + 31543843 = 31543896
67 + 31543829 = 31543896
79 + 31543817 = 31543896
113 + 31543783 = 31543896
127 + 31543769 = 31543896

Showing the first eight; more decompositions exist.
