Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947920, here are decompositions:

3 + 947917 = 947920
47 + 947873 = 947920
59 + 947861 = 947920
101 + 947819 = 947920
137 + 947783 = 947920
167 + 947753 = 947920
173 + 947747 = 947920
179 + 947741 = 947920

Showing the first eight; more decompositions exist.
