Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498842, here are decompositions:

61 + 498781 = 498842
103 + 498739 = 498842
109 + 498733 = 498842
151 + 498691 = 498842
163 + 498679 = 498842
199 + 498643 = 498842
229 + 498613 = 498842
349 + 498493 = 498842

Showing the first eight; more decompositions exist.
