Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495008, here are decompositions:

109 + 494899 = 495008
271 + 494737 = 495008
277 + 494731 = 495008
331 + 494677 = 495008
337 + 494671 = 495008
421 + 494587 = 495008
487 + 494521 = 495008
601 + 494407 = 495008

Showing the first eight; more decompositions exist.
