Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613976, here are decompositions:

13 + 31613963 = 31613976
109 + 31613867 = 31613976
137 + 31613839 = 31613976
157 + 31613819 = 31613976
179 + 31613797 = 31613976
193 + 31613783 = 31613976
257 + 31613719 = 31613976
307 + 31613669 = 31613976

Showing the first eight; more decompositions exist.
