Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627206, here are decompositions:

5 + 31627201 = 31627206
73 + 31627133 = 31627206
137 + 31627069 = 31627206
173 + 31627033 = 31627206
179 + 31627027 = 31627206
199 + 31627007 = 31627206
227 + 31626979 = 31627206
229 + 31626977 = 31627206

Showing the first eight; more decompositions exist.
