Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665492, here are decompositions:

23 + 8665469 = 8665492
41 + 8665451 = 8665492
83 + 8665409 = 8665492
131 + 8665361 = 8665492
179 + 8665313 = 8665492
233 + 8665259 = 8665492
239 + 8665253 = 8665492
383 + 8665109 = 8665492

Showing the first eight; more decompositions exist.
