Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497988, here are decompositions:

11 + 497977 = 497988
19 + 497969 = 497988
31 + 497957 = 497988
59 + 497929 = 497988
89 + 497899 = 497988
137 + 497851 = 497988
149 + 497839 = 497988
157 + 497831 = 497988

Showing the first eight; more decompositions exist.
