Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54138, here are decompositions:

5 + 54133 = 54138
17 + 54121 = 54138
37 + 54101 = 54138
47 + 54091 = 54138
79 + 54059 = 54138
89 + 54049 = 54138
101 + 54037 = 54138
127 + 54011 = 54138

Showing the first eight; more decompositions exist.
