Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563662, here are decompositions:

61 + 31563601 = 31563662
199 + 31563463 = 31563662
211 + 31563451 = 31563662
271 + 31563391 = 31563662
313 + 31563349 = 31563662
379 + 31563283 = 31563662
409 + 31563253 = 31563662
499 + 31563163 = 31563662

Showing the first eight; more decompositions exist.
