Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498558, here are decompositions:

7 + 498551 = 498558
31 + 498527 = 498558
37 + 498521 = 498558
61 + 498497 = 498558
89 + 498469 = 498558
97 + 498461 = 498558
149 + 498409 = 498558
157 + 498401 = 498558

Showing the first eight; more decompositions exist.
