Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961782, here are decompositions:

5 + 961777 = 961782
13 + 961769 = 961782
43 + 961739 = 961782
53 + 961729 = 961782
79 + 961703 = 961782
103 + 961679 = 961782
139 + 961643 = 961782
149 + 961633 = 961782

Showing the first eight; more decompositions exist.
