Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995778, here are decompositions:

31 + 995747 = 995778
41 + 995737 = 995778
59 + 995719 = 995778
79 + 995699 = 995778
101 + 995677 = 995778
109 + 995669 = 995778
127 + 995651 = 995778
137 + 995641 = 995778

Showing the first eight; more decompositions exist.
