Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563674, here are decompositions:

3 + 31563671 = 31563674
73 + 31563601 = 31563674
211 + 31563463 = 31563674
223 + 31563451 = 31563674
271 + 31563403 = 31563674
283 + 31563391 = 31563674
397 + 31563277 = 31563674
421 + 31563253 = 31563674

Showing the first eight; more decompositions exist.
