Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945840, here are decompositions:

17 + 945823 = 945840
23 + 945817 = 945840
29 + 945811 = 945840
31 + 945809 = 945840
41 + 945799 = 945840
53 + 945787 = 945840
73 + 945767 = 945840
101 + 945739 = 945840

Showing the first eight; more decompositions exist.
