Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947890, here are decompositions:

17 + 947873 = 947890
29 + 947861 = 947890
71 + 947819 = 947890
107 + 947783 = 947890
137 + 947753 = 947890
149 + 947741 = 947890
179 + 947711 = 947890
239 + 947651 = 947890

Showing the first eight; more decompositions exist.
