Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73210, here are decompositions:

29 + 73181 = 73210
83 + 73127 = 73210
89 + 73121 = 73210
131 + 73079 = 73210
149 + 73061 = 73210
167 + 73043 = 73210
173 + 73037 = 73210
191 + 73019 = 73210

Showing the first eight; more decompositions exist.
