Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73240, here are decompositions:

3 + 73237 = 73240
59 + 73181 = 73240
107 + 73133 = 73240
113 + 73127 = 73240
149 + 73091 = 73240
179 + 73061 = 73240
197 + 73043 = 73240
227 + 73013 = 73240

Showing the first eight; more decompositions exist.
