Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554846, here are decompositions:

5 + 31554841 = 31554846
17 + 31554829 = 31554846
23 + 31554823 = 31554846
97 + 31554749 = 31554846
107 + 31554739 = 31554846
137 + 31554709 = 31554846
179 + 31554667 = 31554846
227 + 31554619 = 31554846

Showing the first eight; more decompositions exist.
