Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482182, here are decompositions:

3 + 31482179 = 31482182
13 + 31482169 = 31482182
79 + 31482103 = 31482182
139 + 31482043 = 31482182
271 + 31481911 = 31482182
283 + 31481899 = 31482182
331 + 31481851 = 31482182
439 + 31481743 = 31482182

Showing the first eight; more decompositions exist.
