Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611600, here are decompositions:

3 + 8611597 = 8611600
71 + 8611529 = 8611600
113 + 8611487 = 8611600
167 + 8611433 = 8611600
197 + 8611403 = 8611600
251 + 8611349 = 8611600
269 + 8611331 = 8611600
293 + 8611307 = 8611600

Showing the first eight; more decompositions exist.
