Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996780, here are decompositions:

17 + 996763 = 996780
41 + 996739 = 996780
131 + 996649 = 996780
149 + 996631 = 996780
151 + 996629 = 996780
163 + 996617 = 996780
179 + 996601 = 996780
181 + 996599 = 996780

Showing the first eight; more decompositions exist.
