Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661436, here are decompositions:

23 + 8661413 = 8661436
29 + 8661407 = 8661436
53 + 8661383 = 8661436
83 + 8661353 = 8661436
197 + 8661239 = 8661436
233 + 8661203 = 8661436
239 + 8661197 = 8661436
263 + 8661173 = 8661436

Showing the first eight; more decompositions exist.
