Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578256, here are decompositions:

5 + 578251 = 578256
43 + 578213 = 578256
47 + 578209 = 578256
53 + 578203 = 578256
73 + 578183 = 578256
89 + 578167 = 578256
139 + 578117 = 578256
163 + 578093 = 578256

Showing the first eight; more decompositions exist.
