Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608048, here are decompositions:

7 + 31608041 = 31608048
11 + 31608037 = 31608048
19 + 31608029 = 31608048
79 + 31607969 = 31608048
127 + 31607921 = 31608048
139 + 31607909 = 31608048
151 + 31607897 = 31608048
179 + 31607869 = 31608048

Showing the first eight; more decompositions exist.
