Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581084, here are decompositions:

13 + 581071 = 581084
37 + 581047 = 581084
43 + 581041 = 581084
103 + 580981 = 581084
157 + 580927 = 581084
193 + 580891 = 581084
241 + 580843 = 581084
271 + 580813 = 581084

Showing the first eight; more decompositions exist.
