Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484344, here are decompositions:

5 + 31484339 = 31484344
41 + 31484303 = 31484344
107 + 31484237 = 31484344
137 + 31484207 = 31484344
167 + 31484177 = 31484344
251 + 31484093 = 31484344
263 + 31484081 = 31484344
431 + 31483913 = 31484344

Showing the first eight; more decompositions exist.
