Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998744, here are decompositions:

7 + 998737 = 998744
127 + 998617 = 998744
193 + 998551 = 998744
367 + 998377 = 998744
433 + 998311 = 998744
457 + 998287 = 998744
463 + 998281 = 998744
547 + 998197 = 998744

Showing the first eight; more decompositions exist.
