Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951666, here are decompositions:

7 + 951659 = 951666
17 + 951649 = 951666
19 + 951647 = 951666
29 + 951637 = 951666
43 + 951623 = 951666
83 + 951583 = 951666
109 + 951557 = 951666
113 + 951553 = 951666

Showing the first eight; more decompositions exist.
