Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598030, here are decompositions:

3 + 31598027 = 31598030
19 + 31598011 = 31598030
43 + 31597987 = 31598030
97 + 31597933 = 31598030
103 + 31597927 = 31598030
151 + 31597879 = 31598030
157 + 31597873 = 31598030
229 + 31597801 = 31598030

Showing the first eight; more decompositions exist.
