Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482164, here are decompositions:

61 + 31482103 = 31482164
67 + 31482097 = 31482164
97 + 31482067 = 31482164
127 + 31482037 = 31482164
151 + 31482013 = 31482164
277 + 31481887 = 31482164
313 + 31481851 = 31482164
397 + 31481767 = 31482164

Showing the first eight; more decompositions exist.
