Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498450, here are decompositions:

23 + 31498427 = 31498450
29 + 31498421 = 31498450
83 + 31498367 = 31498450
101 + 31498349 = 31498450
107 + 31498343 = 31498450
173 + 31498277 = 31498450
197 + 31498253 = 31498450
233 + 31498217 = 31498450

Showing the first eight; more decompositions exist.
