Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581376, here are decompositions:

7 + 581369 = 581376
23 + 581353 = 581376
43 + 581333 = 581376
53 + 581323 = 581376
73 + 581303 = 581376
83 + 581293 = 581376
113 + 581263 = 581376
137 + 581239 = 581376

Showing the first eight; more decompositions exist.
