Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498444, here are decompositions:

17 + 31498427 = 31498444
23 + 31498421 = 31498444
101 + 31498343 = 31498444
137 + 31498307 = 31498444
167 + 31498277 = 31498444
191 + 31498253 = 31498444
227 + 31498217 = 31498444
251 + 31498193 = 31498444

Showing the first eight; more decompositions exist.
