Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576146, here are decompositions:

29 + 31576117 = 31576146
59 + 31576087 = 31576146
79 + 31576067 = 31576146
97 + 31576049 = 31576146
109 + 31576037 = 31576146
137 + 31576009 = 31576146
139 + 31576007 = 31576146
223 + 31575923 = 31576146

Showing the first eight; more decompositions exist.
