Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578450, here are decompositions:

31 + 578419 = 578450
43 + 578407 = 578450
79 + 578371 = 578450
97 + 578353 = 578450
139 + 578311 = 578450
151 + 578299 = 578450
199 + 578251 = 578450
241 + 578209 = 578450

Showing the first eight; more decompositions exist.
