Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482122, here are decompositions:

3 + 31482119 = 31482122
19 + 31482103 = 31482122
79 + 31482043 = 31482122
109 + 31482013 = 31482122
211 + 31481911 = 31482122
223 + 31481899 = 31482122
271 + 31481851 = 31482122
379 + 31481743 = 31482122

Showing the first eight; more decompositions exist.
