Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947728, here are decompositions:

17 + 947711 = 947728
101 + 947627 = 947728
107 + 947621 = 947728
149 + 947579 = 947728
167 + 947561 = 947728
227 + 947501 = 947728
311 + 947417 = 947728
317 + 947411 = 947728

Showing the first eight; more decompositions exist.
