Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998522, here are decompositions:

79 + 998443 = 998522
103 + 998419 = 998522
193 + 998329 = 998522
211 + 998311 = 998522
241 + 998281 = 998522
439 + 998083 = 998522
631 + 997891 = 998522
643 + 997879 = 998522

Showing the first eight; more decompositions exist.
