Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482070, here are decompositions:

3 + 31482067 = 31482070
23 + 31482047 = 31482070
29 + 31482041 = 31482070
89 + 31481981 = 31482070
131 + 31481939 = 31482070
149 + 31481921 = 31482070
227 + 31481843 = 31482070
233 + 31481837 = 31482070

Showing the first eight; more decompositions exist.
