Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581252, here are decompositions:

13 + 581239 = 581252
79 + 581173 = 581252
103 + 581149 = 581252
109 + 581143 = 581252
151 + 581101 = 581252
163 + 581089 = 581252
181 + 581071 = 581252
211 + 581041 = 581252

Showing the first eight; more decompositions exist.
