Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581248, here are decompositions:

11 + 581237 = 581248
47 + 581201 = 581248
71 + 581177 = 581248
149 + 581099 = 581248
179 + 581069 = 581248
251 + 580997 = 581248
347 + 580901 = 581248
359 + 580889 = 581248

Showing the first eight; more decompositions exist.
