Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563446, here are decompositions:

3 + 31563443 = 31563446
43 + 31563403 = 31563446
97 + 31563349 = 31563446
163 + 31563283 = 31563446
193 + 31563253 = 31563446
283 + 31563163 = 31563446
373 + 31563073 = 31563446
433 + 31563013 = 31563446

Showing the first eight; more decompositions exist.
