Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677872, here are decompositions:

31 + 8677841 = 8677872
43 + 8677829 = 8677872
101 + 8677771 = 8677872
109 + 8677763 = 8677872
113 + 8677759 = 8677872
149 + 8677723 = 8677872
191 + 8677681 = 8677872
389 + 8677483 = 8677872

Showing the first eight; more decompositions exist.
