Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495122, here are decompositions:

3 + 495119 = 495122
13 + 495109 = 495122
79 + 495043 = 495122
163 + 494959 = 495122
223 + 494899 = 495122
373 + 494749 = 495122
379 + 494743 = 495122
409 + 494713 = 495122

Showing the first eight; more decompositions exist.
