Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497642, here are decompositions:

151 + 497491 = 497642
163 + 497479 = 497642
181 + 497461 = 497642
193 + 497449 = 497642
373 + 497269 = 497642
601 + 497041 = 497642
631 + 497011 = 497642
643 + 496999 = 497642

Showing the first eight; more decompositions exist.
