Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011898, here are decompositions:

5 + 1011893 = 1011898
71 + 1011827 = 1011898
101 + 1011797 = 1011898
149 + 1011749 = 1011898
179 + 1011719 = 1011898
227 + 1011671 = 1011898
257 + 1011641 = 1011898
311 + 1011587 = 1011898

Showing the first eight; more decompositions exist.
