Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613910, here are decompositions:

43 + 31613867 = 31613910
67 + 31613843 = 31613910
71 + 31613839 = 31613910
103 + 31613807 = 31613910
109 + 31613801 = 31613910
113 + 31613797 = 31613910
127 + 31613783 = 31613910
191 + 31613719 = 31613910

Showing the first eight; more decompositions exist.
