Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009940, here are decompositions:

3 + 1009937 = 1009940
13 + 1009927 = 1009940
31 + 1009909 = 1009940
67 + 1009873 = 1009940
97 + 1009843 = 1009940
103 + 1009837 = 1009940
193 + 1009747 = 1009940
199 + 1009741 = 1009940

Showing the first eight; more decompositions exist.
