Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626318, here are decompositions:

71 + 31626247 = 31626318
89 + 31626229 = 31626318
109 + 31626209 = 31626318
127 + 31626191 = 31626318
151 + 31626167 = 31626318
239 + 31626079 = 31626318
277 + 31626041 = 31626318
307 + 31626011 = 31626318

Showing the first eight; more decompositions exist.
