Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947420, here are decompositions:

3 + 947417 = 947420
7 + 947413 = 947420
13 + 947407 = 947420
31 + 947389 = 947420
37 + 947383 = 947420
43 + 947377 = 947420
79 + 947341 = 947420
157 + 947263 = 947420

Showing the first eight; more decompositions exist.
