Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73100, here are decompositions:

37 + 73063 = 73100
61 + 73039 = 73100
103 + 72997 = 73100
127 + 72973 = 73100
151 + 72949 = 73100
163 + 72937 = 73100
193 + 72907 = 73100
199 + 72901 = 73100

Showing the first eight; more decompositions exist.
