Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497388, here are decompositions:

37 + 497351 = 497388
79 + 497309 = 497388
97 + 497291 = 497388
107 + 497281 = 497388
109 + 497279 = 497388
127 + 497261 = 497388
131 + 497257 = 497388
149 + 497239 = 497388

Showing the first eight; more decompositions exist.
