Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498518, here are decompositions:

79 + 498439 = 498518
109 + 498409 = 498518
127 + 498391 = 498518
151 + 498367 = 498518
157 + 498361 = 498518
337 + 498181 = 498518
457 + 498061 = 498518
541 + 497977 = 498518

Showing the first eight; more decompositions exist.
