Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947740, here are decompositions:

11 + 947729 = 947740
29 + 947711 = 947740
89 + 947651 = 947740
113 + 947627 = 947740
137 + 947603 = 947740
179 + 947561 = 947740
239 + 947501 = 947740
257 + 947483 = 947740

Showing the first eight; more decompositions exist.
