Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697372, here are decompositions:

29 + 8697343 = 8697372
59 + 8697313 = 8697372
71 + 8697301 = 8697372
109 + 8697263 = 8697372
139 + 8697233 = 8697372
239 + 8697133 = 8697372
269 + 8697103 = 8697372
283 + 8697089 = 8697372

Showing the first eight; more decompositions exist.
