Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947730, here are decompositions:

11 + 947719 = 947730
19 + 947711 = 947730
23 + 947707 = 947730
71 + 947659 = 947730
79 + 947651 = 947730
83 + 947647 = 947730
89 + 947641 = 947730
103 + 947627 = 947730

Showing the first eight; more decompositions exist.
