Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482306, here are decompositions:

13 + 31482293 = 31482306
29 + 31482277 = 31482306
59 + 31482247 = 31482306
127 + 31482179 = 31482306
137 + 31482169 = 31482306
139 + 31482167 = 31482306
223 + 31482083 = 31482306
239 + 31482067 = 31482306

Showing the first eight; more decompositions exist.
