Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498388, here are decompositions:

131 + 498257 = 498388
179 + 498209 = 498388
269 + 498119 = 498388
389 + 497999 = 498388
419 + 497969 = 498388
431 + 497957 = 498388
521 + 497867 = 498388
557 + 497831 = 498388

Showing the first eight; more decompositions exist.
