Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578398, here are decompositions:

71 + 578327 = 578398
89 + 578309 = 578398
101 + 578297 = 578398
131 + 578267 = 578398
281 + 578117 = 578398
419 + 577979 = 578398
461 + 577937 = 578398
467 + 577931 = 578398

Showing the first eight; more decompositions exist.
