Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947644, here are decompositions:

3 + 947641 = 947644
17 + 947627 = 947644
23 + 947621 = 947644
41 + 947603 = 947644
83 + 947561 = 947644
227 + 947417 = 947644
233 + 947411 = 947644
263 + 947381 = 947644

Showing the first eight; more decompositions exist.
