Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516298, here are decompositions:

61 + 31516237 = 31516298
97 + 31516201 = 31516298
109 + 31516189 = 31516298
139 + 31516159 = 31516298
199 + 31516099 = 31516298
211 + 31516087 = 31516298
271 + 31516027 = 31516298
277 + 31516021 = 31516298

Showing the first eight; more decompositions exist.
