Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590264, here are decompositions:

23 + 31590241 = 31590264
53 + 31590211 = 31590264
103 + 31590161 = 31590264
127 + 31590137 = 31590264
131 + 31590133 = 31590264
193 + 31590071 = 31590264
227 + 31590037 = 31590264
257 + 31590007 = 31590264

Showing the first eight; more decompositions exist.
