Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528264, here are decompositions:

23 + 31528241 = 31528264
107 + 31528157 = 31528264
113 + 31528151 = 31528264
137 + 31528127 = 31528264
197 + 31528067 = 31528264
227 + 31528037 = 31528264
263 + 31528001 = 31528264
563 + 31527701 = 31528264

Showing the first eight; more decompositions exist.
