Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998574, here are decompositions:

13 + 998561 = 998574
23 + 998551 = 998574
37 + 998537 = 998574
47 + 998527 = 998574
61 + 998513 = 998574
103 + 998471 = 998574
131 + 998443 = 998574
151 + 998423 = 998574

Showing the first eight; more decompositions exist.
