Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181362, here are decompositions:

59 + 181303 = 181362
61 + 181301 = 181362
79 + 181283 = 181362
89 + 181273 = 181362
109 + 181253 = 181362
149 + 181213 = 181362
151 + 181211 = 181362
163 + 181199 = 181362

Showing the first eight; more decompositions exist.
