Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72166, here are decompositions:

5 + 72161 = 72166
89 + 72077 = 72166
113 + 72053 = 72166
167 + 71999 = 72166
173 + 71993 = 72166
179 + 71987 = 72166
233 + 71933 = 72166
257 + 71909 = 72166

Showing the first eight; more decompositions exist.
