Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699372, here are decompositions:

61 + 8699311 = 8699372
79 + 8699293 = 8699372
103 + 8699269 = 8699372
109 + 8699263 = 8699372
139 + 8699233 = 8699372
193 + 8699179 = 8699372
211 + 8699161 = 8699372
229 + 8699143 = 8699372

Showing the first eight; more decompositions exist.
