Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947902, here are decompositions:

29 + 947873 = 947902
41 + 947861 = 947902
83 + 947819 = 947902
149 + 947753 = 947902
173 + 947729 = 947902
191 + 947711 = 947902
251 + 947651 = 947902
281 + 947621 = 947902

Showing the first eight; more decompositions exist.
