Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498398, here are decompositions:

7 + 498391 = 498398
31 + 498367 = 498398
37 + 498361 = 498398
67 + 498331 = 498398
97 + 498301 = 498398
127 + 498271 = 498398
139 + 498259 = 498398
337 + 498061 = 498398

Showing the first eight; more decompositions exist.
