Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498284, here are decompositions:

5 + 31498279 = 31498284
7 + 31498277 = 31498284
11 + 31498273 = 31498284
31 + 31498253 = 31498284
67 + 31498217 = 31498284
71 + 31498213 = 31498284
173 + 31498111 = 31498284
197 + 31498087 = 31498284

Showing the first eight; more decompositions exist.
