Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484494, here are decompositions:

131 + 31484363 = 31484494
191 + 31484303 = 31484494
227 + 31484267 = 31484494
257 + 31484237 = 31484494
317 + 31484177 = 31484494
401 + 31484093 = 31484494
617 + 31483877 = 31484494
653 + 31483841 = 31484494

Showing the first eight; more decompositions exist.
