Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495148, here are decompositions:

29 + 495119 = 495148
107 + 495041 = 495148
131 + 495017 = 495148
359 + 494789 = 495148
389 + 494759 = 495148
449 + 494699 = 495148
461 + 494687 = 495148
509 + 494639 = 495148

Showing the first eight; more decompositions exist.
