Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677920, here are decompositions:

29 + 8677891 = 8677920
37 + 8677883 = 8677920
73 + 8677847 = 8677920
79 + 8677841 = 8677920
149 + 8677771 = 8677920
157 + 8677763 = 8677920
193 + 8677727 = 8677920
197 + 8677723 = 8677920

Showing the first eight; more decompositions exist.
