Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940940, here are decompositions:

19 + 940921 = 940940
37 + 940903 = 940940
61 + 940879 = 940940
127 + 940813 = 940940
139 + 940801 = 940940
157 + 940783 = 940940
181 + 940759 = 940940
271 + 940669 = 940940

Showing the first eight; more decompositions exist.
