Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497438, here are decompositions:

157 + 497281 = 497438
181 + 497257 = 497438
199 + 497239 = 497438
241 + 497197 = 497438
397 + 497041 = 497438
421 + 497017 = 497438
439 + 496999 = 497438
541 + 496897 = 497438

Showing the first eight; more decompositions exist.
