Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947522, here are decompositions:

13 + 947509 = 947522
73 + 947449 = 947522
109 + 947413 = 947522
139 + 947383 = 947522
181 + 947341 = 947522
223 + 947299 = 947522
283 + 947239 = 947522
439 + 947083 = 947522

Showing the first eight; more decompositions exist.
