Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641526, here are decompositions:

7 + 8641519 = 8641526
13 + 8641513 = 8641526
73 + 8641453 = 8641526
97 + 8641429 = 8641526
199 + 8641327 = 8641526
277 + 8641249 = 8641526
379 + 8641147 = 8641526
433 + 8641093 = 8641526

Showing the first eight; more decompositions exist.
