Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162318, here are decompositions:

29 + 162289 = 162318
31 + 162287 = 162318
41 + 162277 = 162318
61 + 162257 = 162318
67 + 162251 = 162318
89 + 162229 = 162318
97 + 162221 = 162318
109 + 162209 = 162318

Showing the first eight; more decompositions exist.
