Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578458, here are decompositions:

5 + 578453 = 578458
17 + 578441 = 578458
59 + 578399 = 578458
131 + 578327 = 578458
149 + 578309 = 578458
191 + 578267 = 578458
479 + 577979 = 578458
521 + 577937 = 578458

Showing the first eight; more decompositions exist.
