Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661514, here are decompositions:

5 + 8661509 = 8661514
23 + 8661491 = 8661514
53 + 8661461 = 8661514
101 + 8661413 = 8661514
107 + 8661407 = 8661514
131 + 8661383 = 8661514
233 + 8661281 = 8661514
263 + 8661251 = 8661514

Showing the first eight; more decompositions exist.
