Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645392, here are decompositions:

11 + 8645381 = 8645392
131 + 8645261 = 8645392
149 + 8645243 = 8645392
251 + 8645141 = 8645392
269 + 8645123 = 8645392
311 + 8645081 = 8645392
383 + 8645009 = 8645392
401 + 8644991 = 8645392

Showing the first eight; more decompositions exist.
