Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042986, here are decompositions:

37 + 1042949 = 1042986
83 + 1042903 = 1042986
89 + 1042897 = 1042986
137 + 1042849 = 1042986
149 + 1042837 = 1042986
157 + 1042829 = 1042986
167 + 1042819 = 1042986
227 + 1042759 = 1042986

Showing the first eight; more decompositions exist.
