Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548996, here are decompositions:

13 + 31548983 = 31548996
43 + 31548953 = 31548996
139 + 31548857 = 31548996
173 + 31548823 = 31548996
179 + 31548817 = 31548996
229 + 31548767 = 31548996
233 + 31548763 = 31548996
239 + 31548757 = 31548996

Showing the first eight; more decompositions exist.
