Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495898, here are decompositions:

5 + 495893 = 495898
47 + 495851 = 495898
71 + 495827 = 495898
101 + 495797 = 495898
107 + 495791 = 495898
149 + 495749 = 495898
191 + 495707 = 495898
197 + 495701 = 495898

Showing the first eight; more decompositions exist.
