Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497646, here are decompositions:

13 + 497633 = 497646
43 + 497603 = 497646
59 + 497587 = 497646
67 + 497579 = 497646
89 + 497557 = 497646
109 + 497537 = 497646
137 + 497509 = 497646
139 + 497507 = 497646

Showing the first eight; more decompositions exist.
