Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578878, here are decompositions:

17 + 578861 = 578878
59 + 578819 = 578878
89 + 578789 = 578878
101 + 578777 = 578878
137 + 578741 = 578878
149 + 578729 = 578878
191 + 578687 = 578878
257 + 578621 = 578878

Showing the first eight; more decompositions exist.
