Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581336, here are decompositions:

3 + 581333 = 581336
13 + 581323 = 581336
43 + 581293 = 581336
73 + 581263 = 581336
97 + 581239 = 581336
109 + 581227 = 581336
139 + 581197 = 581336
163 + 581173 = 581336

Showing the first eight; more decompositions exist.
