Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520364, here are decompositions:

11 + 31520353 = 31520364
47 + 31520317 = 31520364
131 + 31520233 = 31520364
163 + 31520201 = 31520364
191 + 31520173 = 31520364
193 + 31520171 = 31520364
223 + 31520141 = 31520364
347 + 31520017 = 31520364

Showing the first eight; more decompositions exist.
