Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009946, here are decompositions:

19 + 1009927 = 1009946
37 + 1009909 = 1009946
73 + 1009873 = 1009946
103 + 1009843 = 1009946
109 + 1009837 = 1009946
127 + 1009819 = 1009946
139 + 1009807 = 1009946
199 + 1009747 = 1009946

Showing the first eight; more decompositions exist.
