Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162176, here are decompositions:

67 + 162109 = 162176
97 + 162079 = 162176
193 + 161983 = 162176
199 + 161977 = 162176
229 + 161947 = 162176
307 + 161869 = 162176
337 + 161839 = 162176
397 + 161779 = 162176

Showing the first eight; more decompositions exist.
