Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495140, here are decompositions:

7 + 495133 = 495140
31 + 495109 = 495140
73 + 495067 = 495140
97 + 495043 = 495140
103 + 495037 = 495140
181 + 494959 = 495140
223 + 494917 = 495140
241 + 494899 = 495140

Showing the first eight; more decompositions exist.
