Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608840, here are decompositions:

3 + 8608837 = 8608840
11 + 8608829 = 8608840
17 + 8608823 = 8608840
41 + 8608799 = 8608840
89 + 8608751 = 8608840
113 + 8608727 = 8608840
167 + 8608673 = 8608840
173 + 8608667 = 8608840

Showing the first eight; more decompositions exist.
