Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581364, here are decompositions:

11 + 581353 = 581364
13 + 581351 = 581364
23 + 581341 = 581364
31 + 581333 = 581364
41 + 581323 = 581364
53 + 581311 = 581364
61 + 581303 = 581364
71 + 581293 = 581364

Showing the first eight; more decompositions exist.
