Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581088, here are decompositions:

17 + 581071 = 581088
19 + 581069 = 581088
41 + 581047 = 581088
47 + 581041 = 581088
59 + 581029 = 581088
107 + 580981 = 581088
149 + 580939 = 581088
197 + 580891 = 581088

Showing the first eight; more decompositions exist.
