Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482042, here are decompositions:

5 + 31482037 = 31482042
29 + 31482013 = 31482042
61 + 31481981 = 31482042
103 + 31481939 = 31482042
131 + 31481911 = 31482042
191 + 31481851 = 31482042
199 + 31481843 = 31482042
211 + 31481831 = 31482042

Showing the first eight; more decompositions exist.
