Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961778, here are decompositions:

31 + 961747 = 961778
151 + 961627 = 961778
211 + 961567 = 961778
229 + 961549 = 961778
271 + 961507 = 961778
331 + 961447 = 961778
379 + 961399 = 961778
439 + 961339 = 961778

Showing the first eight; more decompositions exist.
