Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182144, here are decompositions:

3 + 182141 = 182144
13 + 182131 = 182144
37 + 182107 = 182144
43 + 182101 = 182144
97 + 182047 = 182144
103 + 182041 = 182144
163 + 181981 = 182144
241 + 181903 = 182144

Showing the first eight; more decompositions exist.
