Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699920, here are decompositions:

3 + 8699917 = 8699920
41 + 8699879 = 8699920
107 + 8699813 = 8699920
113 + 8699807 = 8699920
149 + 8699771 = 8699920
167 + 8699753 = 8699920
197 + 8699723 = 8699920
347 + 8699573 = 8699920

Showing the first eight; more decompositions exist.
