Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961928, here are decompositions:

67 + 961861 = 961928
139 + 961789 = 961928
151 + 961777 = 961928
181 + 961747 = 961928
199 + 961729 = 961928
241 + 961687 = 961928
271 + 961657 = 961928
379 + 961549 = 961928

Showing the first eight; more decompositions exist.
