Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581132, here are decompositions:

31 + 581101 = 581132
43 + 581089 = 581132
61 + 581071 = 581132
103 + 581029 = 581132
151 + 580981 = 581132
163 + 580969 = 581132
193 + 580939 = 581132
241 + 580891 = 581132

Showing the first eight; more decompositions exist.
