Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998516, here are decompositions:

3 + 998513 = 998516
19 + 998497 = 998516
73 + 998443 = 998516
97 + 998419 = 998516
139 + 998377 = 998516
163 + 998353 = 998516
229 + 998287 = 998516
349 + 998167 = 998516

Showing the first eight; more decompositions exist.
