Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626112, here are decompositions:

3 + 31626109 = 31626112
59 + 31626053 = 31626112
71 + 31626041 = 31626112
101 + 31626011 = 31626112
131 + 31625981 = 31626112
149 + 31625963 = 31626112
173 + 31625939 = 31626112
263 + 31625849 = 31626112

Showing the first eight; more decompositions exist.
