Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578820, here are decompositions:

17 + 578803 = 578820
31 + 578789 = 578820
41 + 578779 = 578820
43 + 578777 = 578820
79 + 578741 = 578820
101 + 578719 = 578820
127 + 578693 = 578820
131 + 578689 = 578820

Showing the first eight; more decompositions exist.
