Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581316, here are decompositions:

5 + 581311 = 581316
13 + 581303 = 581316
23 + 581293 = 581316
53 + 581263 = 581316
79 + 581237 = 581316
89 + 581227 = 581316
139 + 581177 = 581316
167 + 581149 = 581316

Showing the first eight; more decompositions exist.
