Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961278, here are decompositions:

5 + 961273 = 961278
37 + 961241 = 961278
89 + 961189 = 961278
127 + 961151 = 961278
137 + 961141 = 961278
139 + 961139 = 961278
179 + 961099 = 961278
181 + 961097 = 961278

Showing the first eight; more decompositions exist.
