Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947488, here are decompositions:

5 + 947483 = 947488
71 + 947417 = 947488
107 + 947381 = 947488
131 + 947357 = 947488
137 + 947351 = 947488
317 + 947171 = 947488
359 + 947129 = 947488
461 + 947027 = 947488

Showing the first eight; more decompositions exist.
