Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73218, here are decompositions:

29 + 73189 = 73218
37 + 73181 = 73218
97 + 73121 = 73218
127 + 73091 = 73218
139 + 73079 = 73218
157 + 73061 = 73218
179 + 73039 = 73218
181 + 73037 = 73218

Showing the first eight; more decompositions exist.
