Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699180, here are decompositions:

13 + 8699167 = 8699180
19 + 8699161 = 8699180
37 + 8699143 = 8699180
67 + 8699113 = 8699180
103 + 8699077 = 8699180
211 + 8698969 = 8699180
241 + 8698939 = 8699180
349 + 8698831 = 8699180

Showing the first eight; more decompositions exist.
