Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598198, here are decompositions:

7 + 31598191 = 31598198
19 + 31598179 = 31598198
61 + 31598137 = 31598198
97 + 31598101 = 31598198
211 + 31597987 = 31598198
271 + 31597927 = 31598198
397 + 31597801 = 31598198
421 + 31597777 = 31598198

Showing the first eight; more decompositions exist.
