Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578978, here are decompositions:

7 + 578971 = 578978
19 + 578959 = 578978
61 + 578917 = 578978
97 + 578881 = 578978
139 + 578839 = 578978
151 + 578827 = 578978
157 + 578821 = 578978
199 + 578779 = 578978

Showing the first eight; more decompositions exist.
