Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54918, here are decompositions:

11 + 54907 = 54918
37 + 54881 = 54918
41 + 54877 = 54918
67 + 54851 = 54918
89 + 54829 = 54918
131 + 54787 = 54918
139 + 54779 = 54918
151 + 54767 = 54918

Showing the first eight; more decompositions exist.
