Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486024, here are decompositions:

71 + 31485953 = 31486024
83 + 31485941 = 31486024
107 + 31485917 = 31486024
131 + 31485893 = 31486024
191 + 31485833 = 31486024
233 + 31485791 = 31486024
257 + 31485767 = 31486024
281 + 31485743 = 31486024

Showing the first eight; more decompositions exist.
