Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497998, here are decompositions:

5 + 497993 = 497998
29 + 497969 = 497998
41 + 497957 = 497998
131 + 497867 = 497998
167 + 497831 = 497998
197 + 497801 = 497998
227 + 497771 = 497998
257 + 497741 = 497998

Showing the first eight; more decompositions exist.
