Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495972, here are decompositions:

5 + 495967 = 495972
13 + 495959 = 495972
19 + 495953 = 495972
41 + 495931 = 495972
73 + 495899 = 495972
79 + 495893 = 495972
151 + 495821 = 495972
173 + 495799 = 495972

Showing the first eight; more decompositions exist.
