Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482072, here are decompositions:

5 + 31482067 = 31482072
29 + 31482043 = 31482072
31 + 31482041 = 31482072
59 + 31482013 = 31482072
151 + 31481921 = 31482072
173 + 31481899 = 31482072
229 + 31481843 = 31482072
241 + 31481831 = 31482072

Showing the first eight; more decompositions exist.
