Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54180, here are decompositions:

13 + 54167 = 54180
17 + 54163 = 54180
29 + 54151 = 54180
41 + 54139 = 54180
47 + 54133 = 54180
59 + 54121 = 54180
79 + 54101 = 54180
89 + 54091 = 54180

Showing the first eight; more decompositions exist.
