Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498538, here are decompositions:

11 + 498527 = 498538
17 + 498521 = 498538
41 + 498497 = 498538
71 + 498467 = 498538
137 + 498401 = 498538
281 + 498257 = 498538
311 + 498227 = 498538
419 + 498119 = 498538

Showing the first eight; more decompositions exist.
