Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698920, here are decompositions:

31 + 8698889 = 8698920
59 + 8698861 = 8698920
79 + 8698841 = 8698920
89 + 8698831 = 8698920
101 + 8698819 = 8698920
107 + 8698813 = 8698920
157 + 8698763 = 8698920
163 + 8698757 = 8698920

Showing the first eight; more decompositions exist.
