Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484248, here are decompositions:

11 + 31484237 = 31484248
41 + 31484207 = 31484248
71 + 31484177 = 31484248
167 + 31484081 = 31484248
179 + 31484069 = 31484248
269 + 31483979 = 31484248
359 + 31483889 = 31484248
449 + 31483799 = 31484248

Showing the first eight; more decompositions exist.
