Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484470, here are decompositions:

53 + 31484417 = 31484470
107 + 31484363 = 31484470
131 + 31484339 = 31484470
167 + 31484303 = 31484470
233 + 31484237 = 31484470
263 + 31484207 = 31484470
293 + 31484177 = 31484470
389 + 31484081 = 31484470

Showing the first eight; more decompositions exist.
