Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998588, here are decompositions:

37 + 998551 = 998588
61 + 998527 = 998588
211 + 998377 = 998588
277 + 998311 = 998588
307 + 998281 = 998588
421 + 998167 = 998588
571 + 998017 = 998588
691 + 997897 = 998588

Showing the first eight; more decompositions exist.
