Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961812, here are decompositions:

23 + 961789 = 961812
29 + 961783 = 961812
43 + 961769 = 961812
73 + 961739 = 961812
79 + 961733 = 961812
83 + 961729 = 961812
109 + 961703 = 961812
149 + 961663 = 961812

Showing the first eight; more decompositions exist.
