Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998648, here are decompositions:

19 + 998629 = 998648
31 + 998617 = 998648
97 + 998551 = 998648
109 + 998539 = 998648
151 + 998497 = 998648
229 + 998419 = 998648
271 + 998377 = 998648
337 + 998311 = 998648

Showing the first eight; more decompositions exist.
