Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183148, here are decompositions:

29 + 183119 = 183148
59 + 183089 = 183148
89 + 183059 = 183148
101 + 183047 = 183148
107 + 183041 = 183148
149 + 182999 = 183148
167 + 182981 = 183148
179 + 182969 = 183148

Showing the first eight; more decompositions exist.
