Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998600, here are decompositions:

61 + 998539 = 998600
73 + 998527 = 998600
103 + 998497 = 998600
157 + 998443 = 998600
181 + 998419 = 998600
223 + 998377 = 998600
271 + 998329 = 998600
313 + 998287 = 998600

Showing the first eight; more decompositions exist.
