Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482138, here are decompositions:

19 + 31482119 = 31482138
41 + 31482097 = 31482138
71 + 31482067 = 31482138
97 + 31482041 = 31482138
101 + 31482037 = 31482138
157 + 31481981 = 31482138
199 + 31481939 = 31482138
227 + 31481911 = 31482138

Showing the first eight; more decompositions exist.
