Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968990, here are decompositions:

19 + 968971 = 968990
31 + 968959 = 968990
73 + 968917 = 968990
79 + 968911 = 968990
163 + 968827 = 968990
181 + 968809 = 968990
229 + 968761 = 968990
277 + 968713 = 968990

Showing the first eight; more decompositions exist.
