Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538226, here are decompositions:

19 + 31538207 = 31538226
23 + 31538203 = 31538226
73 + 31538153 = 31538226
89 + 31538137 = 31538226
113 + 31538113 = 31538226
163 + 31538063 = 31538226
173 + 31538053 = 31538226
179 + 31538047 = 31538226

Showing the first eight; more decompositions exist.
