Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581324, here are decompositions:

13 + 581311 = 581324
31 + 581293 = 581324
61 + 581263 = 581324
97 + 581227 = 581324
127 + 581197 = 581324
151 + 581173 = 581324
181 + 581143 = 581324
223 + 581101 = 581324

Showing the first eight; more decompositions exist.
