Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498142, here are decompositions:

23 + 498119 = 498142
41 + 498101 = 498142
53 + 498089 = 498142
89 + 498053 = 498142
149 + 497993 = 498142
173 + 497969 = 498142
179 + 497963 = 498142
269 + 497873 = 498142

Showing the first eight; more decompositions exist.
