Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661508, here are decompositions:

17 + 8661491 = 8661508
29 + 8661479 = 8661508
47 + 8661461 = 8661508
71 + 8661437 = 8661508
101 + 8661407 = 8661508
197 + 8661311 = 8661508
227 + 8661281 = 8661508
257 + 8661251 = 8661508

Showing the first eight; more decompositions exist.
