Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940920, here are decompositions:

7 + 940913 = 940920
17 + 940903 = 940920
31 + 940889 = 940920
41 + 940879 = 940920
67 + 940853 = 940920
103 + 940817 = 940920
107 + 940813 = 940920
137 + 940783 = 940920

Showing the first eight; more decompositions exist.
