Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497390, here are decompositions:

67 + 497323 = 497390
109 + 497281 = 497390
151 + 497239 = 497390
193 + 497197 = 497390
277 + 497113 = 497390
349 + 497041 = 497390
373 + 497017 = 497390
379 + 497011 = 497390

Showing the first eight; more decompositions exist.
