Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162258, here are decompositions:

7 + 162251 = 162258
29 + 162229 = 162258
37 + 162221 = 162258
139 + 162119 = 162258
149 + 162109 = 162258
167 + 162091 = 162258
179 + 162079 = 162258
199 + 162059 = 162258

Showing the first eight; more decompositions exist.
