Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538148, here are decompositions:

7 + 31538141 = 31538148
11 + 31538137 = 31538148
17 + 31538131 = 31538148
41 + 31538107 = 31538148
101 + 31538047 = 31538148
149 + 31537999 = 31538148
151 + 31537997 = 31538148
167 + 31537981 = 31538148

Showing the first eight; more decompositions exist.
