Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73172, here are decompositions:

31 + 73141 = 73172
109 + 73063 = 73172
163 + 73009 = 73172
199 + 72973 = 73172
223 + 72949 = 73172
241 + 72931 = 73172
271 + 72901 = 73172
283 + 72889 = 73172

Showing the first eight; more decompositions exist.
