Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661598, here are decompositions:

17 + 8661581 = 8661598
41 + 8661557 = 8661598
89 + 8661509 = 8661598
107 + 8661491 = 8661598
137 + 8661461 = 8661598
191 + 8661407 = 8661598
317 + 8661281 = 8661598
347 + 8661251 = 8661598

Showing the first eight; more decompositions exist.
