Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598298, here are decompositions:

19 + 31598279 = 31598298
31 + 31598267 = 31598298
37 + 31598261 = 31598298
59 + 31598239 = 31598298
71 + 31598227 = 31598298
97 + 31598201 = 31598298
107 + 31598191 = 31598298
157 + 31598141 = 31598298

Showing the first eight; more decompositions exist.
