Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497800, here are decompositions:

29 + 497771 = 497800
59 + 497741 = 497800
71 + 497729 = 497800
89 + 497711 = 497800
137 + 497663 = 497800
167 + 497633 = 497800
197 + 497603 = 497800
239 + 497561 = 497800

Showing the first eight; more decompositions exist.
