Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598148, here are decompositions:

5 + 31598143 = 31598148
7 + 31598141 = 31598148
11 + 31598137 = 31598148
47 + 31598101 = 31598148
137 + 31598011 = 31598148
139 + 31598009 = 31598148
151 + 31597997 = 31598148
269 + 31597879 = 31598148

Showing the first eight; more decompositions exist.
