Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485358, here are decompositions:

5 + 31485353 = 31485358
17 + 31485341 = 31485358
89 + 31485269 = 31485358
137 + 31485221 = 31485358
167 + 31485191 = 31485358
251 + 31485107 = 31485358
257 + 31485101 = 31485358
521 + 31484837 = 31485358

Showing the first eight; more decompositions exist.
