Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042940, here are decompositions:

37 + 1042903 = 1042940
43 + 1042897 = 1042940
79 + 1042861 = 1042940
103 + 1042837 = 1042940
181 + 1042759 = 1042940
307 + 1042633 = 1042940
331 + 1042609 = 1042940
421 + 1042519 = 1042940

Showing the first eight; more decompositions exist.
