Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947398, here are decompositions:

17 + 947381 = 947398
29 + 947369 = 947398
41 + 947357 = 947398
47 + 947351 = 947398
71 + 947327 = 947398
227 + 947171 = 947398
269 + 947129 = 947398
401 + 946997 = 947398

Showing the first eight; more decompositions exist.
