Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578428, here are decompositions:

29 + 578399 = 578428
101 + 578327 = 578428
131 + 578297 = 578428
311 + 578117 = 578428
449 + 577979 = 578428
491 + 577937 = 578428
509 + 577919 = 578428
647 + 577781 = 578428

Showing the first eight; more decompositions exist.
