Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527238, here are decompositions:

5 + 31527233 = 31527238
47 + 31527191 = 31527238
89 + 31527149 = 31527238
107 + 31527131 = 31527238
131 + 31527107 = 31527238
191 + 31527047 = 31527238
227 + 31527011 = 31527238
311 + 31526927 = 31527238

Showing the first eight; more decompositions exist.
