Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945822, here are decompositions:

5 + 945817 = 945822
11 + 945811 = 945822
13 + 945809 = 945822
23 + 945799 = 945822
83 + 945739 = 945822
89 + 945733 = 945822
149 + 945673 = 945822
151 + 945671 = 945822

Showing the first eight; more decompositions exist.
