Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482120, here are decompositions:

17 + 31482103 = 31482120
23 + 31482097 = 31482120
31 + 31482089 = 31482120
37 + 31482083 = 31482120
53 + 31482067 = 31482120
73 + 31482047 = 31482120
79 + 31482041 = 31482120
83 + 31482037 = 31482120

Showing the first eight; more decompositions exist.
