Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497440, here are decompositions:

17 + 497423 = 497440
23 + 497417 = 497440
29 + 497411 = 497440
89 + 497351 = 497440
101 + 497339 = 497440
131 + 497309 = 497440
137 + 497303 = 497440
149 + 497291 = 497440

Showing the first eight; more decompositions exist.
