Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578278, here are decompositions:

11 + 578267 = 578278
257 + 578021 = 578278
347 + 577931 = 578278
359 + 577919 = 578278
461 + 577817 = 578278
479 + 577799 = 578278
521 + 577757 = 578278
557 + 577721 = 578278

Showing the first eight; more decompositions exist.
