Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645674, here are decompositions:

5 + 8645669 = 8645674
17 + 8645657 = 8645674
41 + 8645633 = 8645674
131 + 8645543 = 8645674
197 + 8645477 = 8645674
293 + 8645381 = 8645674
347 + 8645327 = 8645674
431 + 8645243 = 8645674

Showing the first eight; more decompositions exist.
