Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498510, here are decompositions:

11 + 31498499 = 31498510
41 + 31498469 = 31498510
47 + 31498463 = 31498510
83 + 31498427 = 31498510
89 + 31498421 = 31498510
167 + 31498343 = 31498510
233 + 31498277 = 31498510
257 + 31498253 = 31498510

Showing the first eight; more decompositions exist.
