Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989960, here are decompositions:

31 + 989929 = 989960
43 + 989917 = 989960
73 + 989887 = 989960
157 + 989803 = 989960
163 + 989797 = 989960
199 + 989761 = 989960
211 + 989749 = 989960
241 + 989719 = 989960

Showing the first eight; more decompositions exist.
