Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998576, here are decompositions:

37 + 998539 = 998576
79 + 998497 = 998576
157 + 998419 = 998576
199 + 998377 = 998576
223 + 998353 = 998576
379 + 998197 = 998576
409 + 998167 = 998576
499 + 998077 = 998576

Showing the first eight; more decompositions exist.
