Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527304, here are decompositions:

71 + 31527233 = 31527304
113 + 31527191 = 31527304
131 + 31527173 = 31527304
173 + 31527131 = 31527304
197 + 31527107 = 31527304
227 + 31527077 = 31527304
257 + 31527047 = 31527304
293 + 31527011 = 31527304

Showing the first eight; more decompositions exist.
