Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611400, here are decompositions:

19 + 8611381 = 8611400
43 + 8611357 = 8611400
79 + 8611321 = 8611400
97 + 8611303 = 8611400
103 + 8611297 = 8611400
139 + 8611261 = 8611400
151 + 8611249 = 8611400
181 + 8611219 = 8611400

Showing the first eight; more decompositions exist.
