Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548138, here are decompositions:

5 + 31548133 = 31548138
29 + 31548109 = 31548138
59 + 31548079 = 31548138
107 + 31548031 = 31548138
109 + 31548029 = 31548138
131 + 31548007 = 31548138
157 + 31547981 = 31548138
179 + 31547959 = 31548138

Showing the first eight; more decompositions exist.
