Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495012, here are decompositions:

53 + 494959 = 495012
73 + 494939 = 495012
79 + 494933 = 495012
109 + 494903 = 495012
113 + 494899 = 495012
139 + 494873 = 495012
163 + 494849 = 495012
223 + 494789 = 495012

Showing the first eight; more decompositions exist.
