Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598150, here are decompositions:

7 + 31598143 = 31598150
13 + 31598137 = 31598150
139 + 31598011 = 31598150
163 + 31597987 = 31598150
223 + 31597927 = 31598150
271 + 31597879 = 31598150
277 + 31597873 = 31598150
307 + 31597843 = 31598150

Showing the first eight; more decompositions exist.
