Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162280, here are decompositions:

3 + 162277 = 162280
11 + 162269 = 162280
17 + 162263 = 162280
23 + 162257 = 162280
29 + 162251 = 162280
59 + 162221 = 162280
71 + 162209 = 162280
137 + 162143 = 162280

Showing the first eight; more decompositions exist.
