Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581304, here are decompositions:

11 + 581293 = 581304
41 + 581263 = 581304
43 + 581261 = 581304
67 + 581237 = 581304
103 + 581201 = 581304
107 + 581197 = 581304
127 + 581177 = 581304
131 + 581173 = 581304

Showing the first eight; more decompositions exist.
