Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498890, here are decompositions:

31 + 498859 = 498890
103 + 498787 = 498890
109 + 498781 = 498890
151 + 498739 = 498890
157 + 498733 = 498890
199 + 498691 = 498890
211 + 498679 = 498890
277 + 498613 = 498890

Showing the first eight; more decompositions exist.
