Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554854, here are decompositions:

3 + 31554851 = 31554854
13 + 31554841 = 31554854
31 + 31554823 = 31554854
43 + 31554811 = 31554854
223 + 31554631 = 31554854
241 + 31554613 = 31554854
271 + 31554583 = 31554854
283 + 31554571 = 31554854

Showing the first eight; more decompositions exist.
