Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944840, here are decompositions:

7 + 944833 = 944840
19 + 944821 = 944840
37 + 944803 = 944840
67 + 944773 = 944840
109 + 944731 = 944840
139 + 944701 = 944840
151 + 944689 = 944840
163 + 944677 = 944840

Showing the first eight; more decompositions exist.
