Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992900, here are decompositions:

37 + 992863 = 992900
43 + 992857 = 992900
163 + 992737 = 992900
193 + 992707 = 992900
199 + 992701 = 992900
211 + 992689 = 992900
241 + 992659 = 992900
277 + 992623 = 992900

Showing the first eight; more decompositions exist.
