Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998532, here are decompositions:

5 + 998527 = 998532
19 + 998513 = 998532
61 + 998471 = 998532
89 + 998443 = 998532
103 + 998429 = 998532
109 + 998423 = 998532
113 + 998419 = 998532
151 + 998381 = 998532

Showing the first eight; more decompositions exist.
