Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538310, here are decompositions:

59 + 31538251 = 31538310
71 + 31538239 = 31538310
103 + 31538207 = 31538310
107 + 31538203 = 31538310
149 + 31538161 = 31538310
157 + 31538153 = 31538310
173 + 31538137 = 31538310
179 + 31538131 = 31538310

Showing the first eight; more decompositions exist.
