Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538084, here are decompositions:

13 + 31538071 = 31538084
31 + 31538053 = 31538084
37 + 31538047 = 31538084
103 + 31537981 = 31538084
163 + 31537921 = 31538084
181 + 31537903 = 31538084
223 + 31537861 = 31538084
241 + 31537843 = 31538084

Showing the first eight; more decompositions exist.
