Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498188, here are decompositions:

7 + 498181 = 498188
127 + 498061 = 498188
199 + 497989 = 498188
211 + 497977 = 498188
337 + 497851 = 498188
349 + 497839 = 498188
487 + 497701 = 498188
499 + 497689 = 498188

Showing the first eight; more decompositions exist.
