Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627270, here are decompositions:

23 + 31627247 = 31627270
53 + 31627217 = 31627270
137 + 31627133 = 31627270
149 + 31627121 = 31627270
179 + 31627091 = 31627270
197 + 31627073 = 31627270
263 + 31627007 = 31627270
293 + 31626977 = 31627270

Showing the first eight; more decompositions exist.
