Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582298, here are decompositions:

31 + 31582267 = 31582298
127 + 31582171 = 31582298
271 + 31582027 = 31582298
277 + 31582021 = 31582298
337 + 31581961 = 31582298
409 + 31581889 = 31582298
421 + 31581877 = 31582298
439 + 31581859 = 31582298

Showing the first eight; more decompositions exist.
