Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563632, here are decompositions:

31 + 31563601 = 31563632
181 + 31563451 = 31563632
229 + 31563403 = 31563632
241 + 31563391 = 31563632
283 + 31563349 = 31563632
349 + 31563283 = 31563632
379 + 31563253 = 31563632
439 + 31563193 = 31563632

Showing the first eight; more decompositions exist.
