Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543996, here are decompositions:

5 + 31543991 = 31543996
17 + 31543979 = 31543996
83 + 31543913 = 31543996
89 + 31543907 = 31543996
137 + 31543859 = 31543996
149 + 31543847 = 31543996
167 + 31543829 = 31543996
179 + 31543817 = 31543996

Showing the first eight; more decompositions exist.
