Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73000, here are decompositions:

3 + 72997 = 73000
23 + 72977 = 73000
41 + 72959 = 73000
47 + 72953 = 73000
89 + 72911 = 73000
107 + 72893 = 73000
131 + 72869 = 73000
233 + 72767 = 73000

Showing the first eight; more decompositions exist.
