Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521064, here are decompositions:

11 + 31521053 = 31521064
167 + 31520897 = 31521064
227 + 31520837 = 31521064
317 + 31520747 = 31521064
647 + 31520417 = 31521064
677 + 31520387 = 31521064
821 + 31520243 = 31521064
863 + 31520201 = 31521064

Showing the first eight; more decompositions exist.
