Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498320, here are decompositions:

19 + 498301 = 498320
61 + 498259 = 498320
139 + 498181 = 498320
157 + 498163 = 498320
307 + 498013 = 498320
331 + 497989 = 498320
421 + 497899 = 498320
547 + 497773 = 498320

Showing the first eight; more decompositions exist.
