Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521032, here are decompositions:

3 + 31521029 = 31521032
31 + 31521001 = 31521032
73 + 31520959 = 31521032
181 + 31520851 = 31521032
271 + 31520761 = 31521032
313 + 31520719 = 31521032
331 + 31520701 = 31521032
373 + 31520659 = 31521032

Showing the first eight; more decompositions exist.
