Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709492, here are decompositions:

23 + 8709469 = 8709492
31 + 8709461 = 8709492
61 + 8709431 = 8709492
109 + 8709383 = 8709492
131 + 8709361 = 8709492
179 + 8709313 = 8709492
191 + 8709301 = 8709492
193 + 8709299 = 8709492

Showing the first eight; more decompositions exist.
