Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498500, here are decompositions:

3 + 498497 = 498500
7 + 498493 = 498500
31 + 498469 = 498500
61 + 498439 = 498500
97 + 498403 = 498500
103 + 498397 = 498500
109 + 498391 = 498500
139 + 498361 = 498500

Showing the first eight; more decompositions exist.
