Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498896, here are decompositions:

17 + 31498879 = 31498896
29 + 31498867 = 31498896
43 + 31498853 = 31498896
47 + 31498849 = 31498896
59 + 31498837 = 31498896
67 + 31498829 = 31498896
83 + 31498813 = 31498896
193 + 31498703 = 31498896

Showing the first eight; more decompositions exist.
