Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482146, here are decompositions:

43 + 31482103 = 31482146
79 + 31482067 = 31482146
103 + 31482043 = 31482146
109 + 31482037 = 31482146
379 + 31481767 = 31482146
433 + 31481713 = 31482146
463 + 31481683 = 31482146
523 + 31481623 = 31482146

Showing the first eight; more decompositions exist.
