Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567298, here are decompositions:

19 + 31567279 = 31567298
31 + 31567267 = 31567298
67 + 31567231 = 31567298
79 + 31567219 = 31567298
211 + 31567087 = 31567298
331 + 31566967 = 31567298
379 + 31566919 = 31567298
397 + 31566901 = 31567298

Showing the first eight; more decompositions exist.
