Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699172, here are decompositions:

5 + 8699167 = 8699172
11 + 8699161 = 8699172
29 + 8699143 = 8699172
59 + 8699113 = 8699172
103 + 8699069 = 8699172
109 + 8699063 = 8699172
199 + 8698973 = 8699172
211 + 8698961 = 8699172

Showing the first eight; more decompositions exist.
