Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494998, here are decompositions:

11 + 494987 = 494998
59 + 494939 = 494998
71 + 494927 = 494998
149 + 494849 = 494998
239 + 494759 = 494998
311 + 494687 = 494998
347 + 494651 = 494998
359 + 494639 = 494998

Showing the first eight; more decompositions exist.
