Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498468, here are decompositions:

5 + 31498463 = 31498468
41 + 31498427 = 31498468
47 + 31498421 = 31498468
101 + 31498367 = 31498468
179 + 31498289 = 31498468
191 + 31498277 = 31498468
251 + 31498217 = 31498468
269 + 31498199 = 31498468

Showing the first eight; more decompositions exist.
