Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548156, here are decompositions:

7 + 31548149 = 31548156
23 + 31548133 = 31548156
47 + 31548109 = 31548156
53 + 31548103 = 31548156
109 + 31548047 = 31548156
127 + 31548029 = 31548156
139 + 31548017 = 31548156
149 + 31548007 = 31548156

Showing the first eight; more decompositions exist.
