Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947800, here are decompositions:

17 + 947783 = 947800
47 + 947753 = 947800
53 + 947747 = 947800
59 + 947741 = 947800
71 + 947729 = 947800
89 + 947711 = 947800
149 + 947651 = 947800
173 + 947627 = 947800

Showing the first eight; more decompositions exist.
