Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498222, here are decompositions:

5 + 31498217 = 31498222
23 + 31498199 = 31498222
29 + 31498193 = 31498222
71 + 31498151 = 31498222
179 + 31498043 = 31498222
281 + 31497941 = 31498222
293 + 31497929 = 31498222
359 + 31497863 = 31498222

Showing the first eight; more decompositions exist.
