Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538204, here are decompositions:

43 + 31538161 = 31538204
67 + 31538137 = 31538204
73 + 31538131 = 31538204
97 + 31538107 = 31538204
151 + 31538053 = 31538204
157 + 31538047 = 31538204
223 + 31537981 = 31538204
283 + 31537921 = 31538204

Showing the first eight; more decompositions exist.
