Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498360, here are decompositions:

11 + 31498349 = 31498360
17 + 31498343 = 31498360
53 + 31498307 = 31498360
71 + 31498289 = 31498360
83 + 31498277 = 31498360
107 + 31498253 = 31498360
167 + 31498193 = 31498360
317 + 31498043 = 31498360

Showing the first eight; more decompositions exist.
