Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000898, here are decompositions:

37 + 1000861 = 1000898
229 + 1000669 = 1000898
277 + 1000621 = 1000898
541 + 1000357 = 1000898
607 + 1000291 = 1000898
727 + 1000171 = 1000898
739 + 1000159 = 1000898
859 + 1000039 = 1000898

Showing the first eight; more decompositions exist.
