Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162146, here are decompositions:

3 + 162143 = 162146
37 + 162109 = 162146
67 + 162079 = 162146
139 + 162007 = 162146
163 + 161983 = 162146
199 + 161947 = 162146
223 + 161923 = 162146
277 + 161869 = 162146

Showing the first eight; more decompositions exist.
