Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54186, here are decompositions:

5 + 54181 = 54186
19 + 54167 = 54186
23 + 54163 = 54186
47 + 54139 = 54186
53 + 54133 = 54186
103 + 54083 = 54186
127 + 54059 = 54186
137 + 54049 = 54186

Showing the first eight; more decompositions exist.
