Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578844, here are decompositions:

5 + 578839 = 578844
17 + 578827 = 578844
23 + 578821 = 578844
41 + 578803 = 578844
67 + 578777 = 578844
103 + 578741 = 578844
151 + 578693 = 578844
157 + 578687 = 578844

Showing the first eight; more decompositions exist.
