Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999838, here are decompositions:

29 + 999809 = 999838
89 + 999749 = 999838
167 + 999671 = 999838
227 + 999611 = 999838
239 + 999599 = 999838
317 + 999521 = 999838
347 + 999491 = 999838
401 + 999437 = 999838

Showing the first eight; more decompositions exist.
