Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947580, here are decompositions:

19 + 947561 = 947580
41 + 947539 = 947580
71 + 947509 = 947580
79 + 947501 = 947580
97 + 947483 = 947580
131 + 947449 = 947580
149 + 947431 = 947580
157 + 947423 = 947580

Showing the first eight; more decompositions exist.
