Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498456, here are decompositions:

29 + 31498427 = 31498456
89 + 31498367 = 31498456
107 + 31498349 = 31498456
113 + 31498343 = 31498456
149 + 31498307 = 31498456
167 + 31498289 = 31498456
179 + 31498277 = 31498456
239 + 31498217 = 31498456

Showing the first eight; more decompositions exist.
