Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495850, here are decompositions:

23 + 495827 = 495850
29 + 495821 = 495850
53 + 495797 = 495850
59 + 495791 = 495850
101 + 495749 = 495850
137 + 495713 = 495850
149 + 495701 = 495850
233 + 495617 = 495850

Showing the first eight; more decompositions exist.
