Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578478, here are decompositions:

11 + 578467 = 578478
37 + 578441 = 578478
59 + 578419 = 578478
71 + 578407 = 578478
79 + 578399 = 578478
107 + 578371 = 578478
151 + 578327 = 578478
167 + 578311 = 578478

Showing the first eight; more decompositions exist.
