Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498366, here are decompositions:

17 + 31498349 = 31498366
23 + 31498343 = 31498366
59 + 31498307 = 31498366
89 + 31498277 = 31498366
113 + 31498253 = 31498366
149 + 31498217 = 31498366
167 + 31498199 = 31498366
173 + 31498193 = 31498366

Showing the first eight; more decompositions exist.
