Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484374, here are decompositions:

11 + 31484363 = 31484374
71 + 31484303 = 31484374
107 + 31484267 = 31484374
137 + 31484237 = 31484374
167 + 31484207 = 31484374
197 + 31484177 = 31484374
281 + 31484093 = 31484374
293 + 31484081 = 31484374

Showing the first eight; more decompositions exist.
