Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498866, here are decompositions:

7 + 498859 = 498866
79 + 498787 = 498866
127 + 498739 = 498866
223 + 498643 = 498866
283 + 498583 = 498866
373 + 498493 = 498866
397 + 498469 = 498866
457 + 498409 = 498866

Showing the first eight; more decompositions exist.
