Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947646, here are decompositions:

5 + 947641 = 947646
19 + 947627 = 947646
43 + 947603 = 947646
67 + 947579 = 947646
107 + 947539 = 947646
137 + 947509 = 947646
163 + 947483 = 947646
197 + 947449 = 947646

Showing the first eight; more decompositions exist.
