Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968840, here are decompositions:

13 + 968827 = 968840
31 + 968809 = 968840
79 + 968761 = 968840
109 + 968731 = 968840
127 + 968713 = 968840
151 + 968689 = 968840
181 + 968659 = 968840
193 + 968647 = 968840

Showing the first eight; more decompositions exist.
