Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501492, here are decompositions:

29 + 501463 = 501492
41 + 501451 = 501492
73 + 501419 = 501492
83 + 501409 = 501492
109 + 501383 = 501492
149 + 501343 = 501492
151 + 501341 = 501492
193 + 501299 = 501492

Showing the first eight; more decompositions exist.
