Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538304, here are decompositions:

43 + 31538261 = 31538304
53 + 31538251 = 31538304
97 + 31538207 = 31538304
101 + 31538203 = 31538304
151 + 31538153 = 31538304
163 + 31538141 = 31538304
167 + 31538137 = 31538304
173 + 31538131 = 31538304

Showing the first eight; more decompositions exist.
