Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482276, here are decompositions:

5 + 31482271 = 31482276
19 + 31482257 = 31482276
29 + 31482247 = 31482276
47 + 31482229 = 31482276
97 + 31482179 = 31482276
103 + 31482173 = 31482276
107 + 31482169 = 31482276
109 + 31482167 = 31482276

Showing the first eight; more decompositions exist.
