Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596880, here are decompositions:

23 + 31596857 = 31596880
41 + 31596839 = 31596880
59 + 31596821 = 31596880
83 + 31596797 = 31596880
131 + 31596749 = 31596880
137 + 31596743 = 31596880
167 + 31596713 = 31596880
173 + 31596707 = 31596880

Showing the first eight; more decompositions exist.
