Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484448, here are decompositions:

31 + 31484417 = 31484448
71 + 31484377 = 31484448
89 + 31484359 = 31484448
109 + 31484339 = 31484448
131 + 31484317 = 31484448
167 + 31484281 = 31484448
181 + 31484267 = 31484448
211 + 31484237 = 31484448

Showing the first eight; more decompositions exist.
