Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485298, here are decompositions:

29 + 31485269 = 31485298
101 + 31485197 = 31485298
107 + 31485191 = 31485298
191 + 31485107 = 31485298
197 + 31485101 = 31485298
239 + 31485059 = 31485298
281 + 31485017 = 31485298
461 + 31484837 = 31485298

Showing the first eight; more decompositions exist.
