Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492938, here are decompositions:

37 + 492901 = 492938
67 + 492871 = 492938
139 + 492799 = 492938
157 + 492781 = 492938
181 + 492757 = 492938
307 + 492631 = 492938
337 + 492601 = 492938
541 + 492397 = 492938

Showing the first eight; more decompositions exist.
