Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520632, here are decompositions:

5 + 31520627 = 31520632
53 + 31520579 = 31520632
113 + 31520519 = 31520632
149 + 31520483 = 31520632
179 + 31520453 = 31520632
233 + 31520399 = 31520632
239 + 31520393 = 31520632
293 + 31520339 = 31520632

Showing the first eight; more decompositions exist.
