Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581584, here are decompositions:

11 + 581573 = 581584
137 + 581447 = 581584
173 + 581411 = 581584
191 + 581393 = 581584
233 + 581351 = 581584
251 + 581333 = 581584
281 + 581303 = 581584
347 + 581237 = 581584

Showing the first eight; more decompositions exist.
