Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595298, here are decompositions:

19 + 31595279 = 31595298
47 + 31595251 = 31595298
61 + 31595237 = 31595298
79 + 31595219 = 31595298
89 + 31595209 = 31595298
109 + 31595189 = 31595298
157 + 31595141 = 31595298
197 + 31595101 = 31595298

Showing the first eight; more decompositions exist.
