Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73138, here are decompositions:

5 + 73133 = 73138
11 + 73127 = 73138
17 + 73121 = 73138
47 + 73091 = 73138
59 + 73079 = 73138
101 + 73037 = 73138
179 + 72959 = 73138
227 + 72911 = 73138

Showing the first eight; more decompositions exist.
