Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623264, here are decompositions:

7 + 31623257 = 31623264
41 + 31623223 = 31623264
53 + 31623211 = 31623264
83 + 31623181 = 31623264
97 + 31623167 = 31623264
151 + 31623113 = 31623264
223 + 31623041 = 31623264
241 + 31623023 = 31623264

Showing the first eight; more decompositions exist.
