Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484298, here are decompositions:

17 + 31484281 = 31484298
31 + 31484267 = 31484298
59 + 31484239 = 31484298
61 + 31484237 = 31484298
89 + 31484209 = 31484298
137 + 31484161 = 31484298
227 + 31484071 = 31484298
229 + 31484069 = 31484298

Showing the first eight; more decompositions exist.
