Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73158, here are decompositions:

17 + 73141 = 73158
31 + 73127 = 73158
37 + 73121 = 73158
67 + 73091 = 73158
79 + 73079 = 73158
97 + 73061 = 73158
139 + 73019 = 73158
149 + 73009 = 73158

Showing the first eight; more decompositions exist.
