Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538044, here are decompositions:

11 + 31538033 = 31538044
47 + 31537997 = 31538044
173 + 31537871 = 31538044
353 + 31537691 = 31538044
563 + 31537481 = 31538044
653 + 31537391 = 31538044
773 + 31537271 = 31538044
821 + 31537223 = 31538044

Showing the first eight; more decompositions exist.
