Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538268, here are decompositions:

7 + 31538261 = 31538268
17 + 31538251 = 31538268
29 + 31538239 = 31538268
61 + 31538207 = 31538268
107 + 31538161 = 31538268
127 + 31538141 = 31538268
131 + 31538137 = 31538268
137 + 31538131 = 31538268

Showing the first eight; more decompositions exist.
