Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947806, here are decompositions:

3 + 947803 = 947806
23 + 947783 = 947806
53 + 947753 = 947806
59 + 947747 = 947806
179 + 947627 = 947806
227 + 947579 = 947806
383 + 947423 = 947806
389 + 947417 = 947806

Showing the first eight; more decompositions exist.
