Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576116, here are decompositions:

29 + 31576087 = 31576116
67 + 31576049 = 31576116
79 + 31576037 = 31576116
107 + 31576009 = 31576116
109 + 31576007 = 31576116
113 + 31576003 = 31576116
179 + 31575937 = 31576116
193 + 31575923 = 31576116

Showing the first eight; more decompositions exist.
