Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578888, here are decompositions:

7 + 578881 = 578888
31 + 578857 = 578888
61 + 578827 = 578888
67 + 578821 = 578888
109 + 578779 = 578888
199 + 578689 = 578888
229 + 578659 = 578888
241 + 578647 = 578888

Showing the first eight; more decompositions exist.
