Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598010, here are decompositions:

13 + 31597997 = 31598010
23 + 31597987 = 31598010
83 + 31597927 = 31598010
97 + 31597913 = 31598010
131 + 31597879 = 31598010
137 + 31597873 = 31598010
167 + 31597843 = 31598010
233 + 31597777 = 31598010

Showing the first eight; more decompositions exist.
