Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498356, here are decompositions:

7 + 31498349 = 31498356
13 + 31498343 = 31498356
67 + 31498289 = 31498356
79 + 31498277 = 31498356
83 + 31498273 = 31498356
103 + 31498253 = 31498356
139 + 31498217 = 31498356
157 + 31498199 = 31498356

Showing the first eight; more decompositions exist.
