Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497986, here are decompositions:

17 + 497969 = 497986
23 + 497963 = 497986
29 + 497957 = 497986
113 + 497873 = 497986
173 + 497813 = 497986
257 + 497729 = 497986
353 + 497633 = 497986
383 + 497603 = 497986

Showing the first eight; more decompositions exist.
