Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498744, here are decompositions:

3 + 31498741 = 31498744
41 + 31498703 = 31498744
197 + 31498547 = 31498744
227 + 31498517 = 31498744
281 + 31498463 = 31498744
317 + 31498427 = 31498744
401 + 31498343 = 31498744
467 + 31498277 = 31498744

Showing the first eight; more decompositions exist.
