Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482078, here are decompositions:

11 + 31482067 = 31482078
31 + 31482047 = 31482078
37 + 31482041 = 31482078
41 + 31482037 = 31482078
97 + 31481981 = 31482078
127 + 31481951 = 31482078
139 + 31481939 = 31482078
157 + 31481921 = 31482078

Showing the first eight; more decompositions exist.
