Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611392, here are decompositions:

11 + 8611381 = 8611392
43 + 8611349 = 8611392
61 + 8611331 = 8611392
71 + 8611321 = 8611392
89 + 8611303 = 8611392
109 + 8611283 = 8611392
131 + 8611261 = 8611392
173 + 8611219 = 8611392

Showing the first eight; more decompositions exist.
