Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947428, here are decompositions:

5 + 947423 = 947428
11 + 947417 = 947428
17 + 947411 = 947428
47 + 947381 = 947428
59 + 947369 = 947428
71 + 947357 = 947428
101 + 947327 = 947428
257 + 947171 = 947428

Showing the first eight; more decompositions exist.
