Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998582, here are decompositions:

31 + 998551 = 998582
43 + 998539 = 998582
139 + 998443 = 998582
163 + 998419 = 998582
229 + 998353 = 998582
271 + 998311 = 998582
421 + 998161 = 998582
499 + 998083 = 998582

Showing the first eight; more decompositions exist.
