Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498566, here are decompositions:

43 + 498523 = 498566
73 + 498493 = 498566
97 + 498469 = 498566
127 + 498439 = 498566
157 + 498409 = 498566
163 + 498403 = 498566
199 + 498367 = 498566
223 + 498343 = 498566

Showing the first eight; more decompositions exist.
