Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947908, here are decompositions:

47 + 947861 = 947908
89 + 947819 = 947908
167 + 947741 = 947908
179 + 947729 = 947908
197 + 947711 = 947908
257 + 947651 = 947908
281 + 947627 = 947908
347 + 947561 = 947908

Showing the first eight; more decompositions exist.
