Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492168, here are decompositions:

101 + 492067 = 492168
107 + 492061 = 492168
109 + 492059 = 492168
139 + 492029 = 492168
151 + 492017 = 492168
191 + 491977 = 492168
199 + 491969 = 492168
269 + 491899 = 492168

Showing the first eight; more decompositions exist.
