Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563554, here are decompositions:

3 + 31563551 = 31563554
103 + 31563451 = 31563554
151 + 31563403 = 31563554
163 + 31563391 = 31563554
271 + 31563283 = 31563554
277 + 31563277 = 31563554
367 + 31563187 = 31563554
523 + 31563031 = 31563554

Showing the first eight; more decompositions exist.
