Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581308, here are decompositions:

5 + 581303 = 581308
47 + 581261 = 581308
71 + 581237 = 581308
107 + 581201 = 581308
131 + 581177 = 581308
137 + 581171 = 581308
239 + 581069 = 581308
311 + 580997 = 581308

Showing the first eight; more decompositions exist.
