Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661448, here are decompositions:

11 + 8661437 = 8661448
41 + 8661407 = 8661448
137 + 8661311 = 8661448
167 + 8661281 = 8661448
197 + 8661251 = 8661448
251 + 8661197 = 8661448
311 + 8661137 = 8661448
359 + 8661089 = 8661448

Showing the first eight; more decompositions exist.
