Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998372, here are decompositions:

19 + 998353 = 998372
43 + 998329 = 998372
61 + 998311 = 998372
211 + 998161 = 998372
409 + 997963 = 998372
439 + 997933 = 998372
631 + 997741 = 998372
673 + 997699 = 998372

Showing the first eight; more decompositions exist.
