Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154180, here are decompositions:

23 + 154157 = 154180
53 + 154127 = 154180
83 + 154097 = 154180
101 + 154079 = 154180
107 + 154073 = 154180
113 + 154067 = 154180
137 + 154043 = 154180
179 + 154001 = 154180

Showing the first eight; more decompositions exist.
