Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73580, here are decompositions:

19 + 73561 = 73580
97 + 73483 = 73580
103 + 73477 = 73580
109 + 73471 = 73580
127 + 73453 = 73580
163 + 73417 = 73580
193 + 73387 = 73580
211 + 73369 = 73580

Showing the first eight; more decompositions exist.
