Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497478, here are decompositions:

5 + 497473 = 497478
17 + 497461 = 497478
29 + 497449 = 497478
61 + 497417 = 497478
67 + 497411 = 497478
89 + 497389 = 497478
127 + 497351 = 497478
139 + 497339 = 497478

Showing the first eight; more decompositions exist.
