Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581036, here are decompositions:

7 + 581029 = 581036
67 + 580969 = 581036
97 + 580939 = 581036
109 + 580927 = 581036
193 + 580843 = 581036
199 + 580837 = 581036
223 + 580813 = 581036
229 + 580807 = 581036

Showing the first eight; more decompositions exist.
