Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182278, here are decompositions:

17 + 182261 = 182278
101 + 182177 = 182278
137 + 182141 = 182278
149 + 182129 = 182278
167 + 182111 = 182278
179 + 182099 = 182278
251 + 182027 = 182278
269 + 182009 = 182278

Showing the first eight; more decompositions exist.
