Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498658, here are decompositions:

5 + 498653 = 498658
11 + 498647 = 498658
47 + 498611 = 498658
59 + 498599 = 498658
101 + 498557 = 498658
107 + 498551 = 498658
131 + 498527 = 498658
137 + 498521 = 498658

Showing the first eight; more decompositions exist.
