Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581064, here are decompositions:

17 + 581047 = 581064
23 + 581041 = 581064
67 + 580997 = 581064
83 + 580981 = 581064
137 + 580927 = 581064
151 + 580913 = 581064
163 + 580901 = 581064
173 + 580891 = 581064

Showing the first eight; more decompositions exist.
