Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54018, here are decompositions:

5 + 54013 = 54018
7 + 54011 = 54018
17 + 54001 = 54018
31 + 53987 = 54018
59 + 53959 = 54018
67 + 53951 = 54018
79 + 53939 = 54018
101 + 53917 = 54018

Showing the first eight; more decompositions exist.
