Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005498, here are decompositions:

5 + 1005493 = 1005498
17 + 1005481 = 1005498
31 + 1005467 = 1005498
41 + 1005457 = 1005498
59 + 1005439 = 1005498
61 + 1005437 = 1005498
71 + 1005427 = 1005498
89 + 1005409 = 1005498

Showing the first eight; more decompositions exist.
