Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998542, here are decompositions:

3 + 998539 = 998542
5 + 998537 = 998542
29 + 998513 = 998542
71 + 998471 = 998542
113 + 998429 = 998542
131 + 998411 = 998542
269 + 998273 = 998542
431 + 998111 = 998542

Showing the first eight; more decompositions exist.
