Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495038, here are decompositions:

79 + 494959 = 495038
139 + 494899 = 495038
277 + 494761 = 495038
307 + 494731 = 495038
367 + 494671 = 495038
421 + 494617 = 495038
499 + 494539 = 495038
541 + 494497 = 495038

Showing the first eight; more decompositions exist.
