Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554896, here are decompositions:

3 + 31554893 = 31554896
7 + 31554889 = 31554896
13 + 31554883 = 31554896
67 + 31554829 = 31554896
73 + 31554823 = 31554896
157 + 31554739 = 31554896
229 + 31554667 = 31554896
277 + 31554619 = 31554896

Showing the first eight; more decompositions exist.
