Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581382, here are decompositions:

5 + 581377 = 581382
13 + 581369 = 581382
29 + 581353 = 581382
31 + 581351 = 581382
41 + 581341 = 581382
59 + 581323 = 581382
71 + 581311 = 581382
79 + 581303 = 581382

Showing the first eight; more decompositions exist.
