Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495212, here are decompositions:

13 + 495199 = 495212
31 + 495181 = 495212
61 + 495151 = 495212
73 + 495139 = 495212
79 + 495133 = 495212
103 + 495109 = 495212
313 + 494899 = 495212
409 + 494803 = 495212

Showing the first eight; more decompositions exist.
