Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011838, here are decompositions:

11 + 1011827 = 1011838
41 + 1011797 = 1011838
59 + 1011779 = 1011838
89 + 1011749 = 1011838
101 + 1011737 = 1011838
167 + 1011671 = 1011838
197 + 1011641 = 1011838
239 + 1011599 = 1011838

Showing the first eight; more decompositions exist.
