Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578872, here are decompositions:

11 + 578861 = 578872
29 + 578843 = 578872
53 + 578819 = 578872
83 + 578789 = 578872
131 + 578741 = 578872
179 + 578693 = 578872
251 + 578621 = 578872
263 + 578609 = 578872

Showing the first eight; more decompositions exist.
