Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477298, here are decompositions:

7 + 31477291 = 31477298
157 + 31477141 = 31477298
199 + 31477099 = 31477298
241 + 31477057 = 31477298
271 + 31477027 = 31477298
277 + 31477021 = 31477298
367 + 31476931 = 31477298
499 + 31476799 = 31477298

Showing the first eight; more decompositions exist.
