Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563824, here are decompositions:

7 + 31563817 = 31563824
31 + 31563793 = 31563824
37 + 31563787 = 31563824
223 + 31563601 = 31563824
373 + 31563451 = 31563824
421 + 31563403 = 31563824
433 + 31563391 = 31563824
541 + 31563283 = 31563824

Showing the first eight; more decompositions exist.
