Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498920, here are decompositions:

13 + 498907 = 498920
61 + 498859 = 498920
139 + 498781 = 498920
181 + 498739 = 498920
229 + 498691 = 498920
241 + 498679 = 498920
277 + 498643 = 498920
307 + 498613 = 498920

Showing the first eight; more decompositions exist.
