Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73168, here are decompositions:

41 + 73127 = 73168
47 + 73121 = 73168
89 + 73079 = 73168
107 + 73061 = 73168
131 + 73037 = 73168
149 + 73019 = 73168
191 + 72977 = 73168
257 + 72911 = 73168

Showing the first eight; more decompositions exist.
