Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485282, here are decompositions:

5 + 31485277 = 31485282
13 + 31485269 = 31485282
61 + 31485221 = 31485282
89 + 31485193 = 31485282
181 + 31485101 = 31485282
223 + 31485059 = 31485282
233 + 31485049 = 31485282
251 + 31485031 = 31485282

Showing the first eight; more decompositions exist.
