Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73040, here are decompositions:

3 + 73037 = 73040
31 + 73009 = 73040
43 + 72997 = 73040
67 + 72973 = 73040
103 + 72937 = 73040
109 + 72931 = 73040
139 + 72901 = 73040
151 + 72889 = 73040

Showing the first eight; more decompositions exist.
