Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494492, here are decompositions:

79 + 494413 = 494492
109 + 494383 = 494492
139 + 494353 = 494492
151 + 494341 = 494492
211 + 494281 = 494492
223 + 494269 = 494492
241 + 494251 = 494492
409 + 494083 = 494492

Showing the first eight; more decompositions exist.
