Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73130, here are decompositions:

3 + 73127 = 73130
67 + 73063 = 73130
157 + 72973 = 73130
181 + 72949 = 73130
193 + 72937 = 73130
199 + 72931 = 73130
223 + 72907 = 73130
229 + 72901 = 73130

Showing the first eight; more decompositions exist.
