Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947388, here are decompositions:

5 + 947383 = 947388
7 + 947381 = 947388
11 + 947377 = 947388
19 + 947369 = 947388
31 + 947357 = 947388
37 + 947351 = 947388
47 + 947341 = 947388
61 + 947327 = 947388

Showing the first eight; more decompositions exist.
