Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452276, here are decompositions:

43 + 31452233 = 31452276
67 + 31452209 = 31452276
73 + 31452203 = 31452276
103 + 31452173 = 31452276
139 + 31452137 = 31452276
179 + 31452097 = 31452276
197 + 31452079 = 31452276
257 + 31452019 = 31452276

Showing the first eight; more decompositions exist.
