Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563614, here are decompositions:

13 + 31563601 = 31563614
151 + 31563463 = 31563614
163 + 31563451 = 31563614
211 + 31563403 = 31563614
223 + 31563391 = 31563614
331 + 31563283 = 31563614
337 + 31563277 = 31563614
421 + 31563193 = 31563614

Showing the first eight; more decompositions exist.
