Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450298, here are decompositions:

7 + 31450291 = 31450298
79 + 31450219 = 31450298
157 + 31450141 = 31450298
181 + 31450117 = 31450298
199 + 31450099 = 31450298
241 + 31450057 = 31450298
277 + 31450021 = 31450298
307 + 31449991 = 31450298

Showing the first eight; more decompositions exist.
