Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498384, here are decompositions:

17 + 31498367 = 31498384
41 + 31498343 = 31498384
107 + 31498277 = 31498384
131 + 31498253 = 31498384
167 + 31498217 = 31498384
191 + 31498193 = 31498384
233 + 31498151 = 31498384
443 + 31497941 = 31498384

Showing the first eight; more decompositions exist.
