Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73140, here are decompositions:

7 + 73133 = 73140
13 + 73127 = 73140
19 + 73121 = 73140
61 + 73079 = 73140
79 + 73061 = 73140
97 + 73043 = 73140
101 + 73039 = 73140
103 + 73037 = 73140

Showing the first eight; more decompositions exist.
