Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497138, here are decompositions:

97 + 497041 = 497138
127 + 497011 = 497138
139 + 496999 = 497138
241 + 496897 = 497138
349 + 496789 = 497138
457 + 496681 = 497138
661 + 496477 = 497138
739 + 496399 = 497138

Showing the first eight; more decompositions exist.
