Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699578, here are decompositions:

5 + 8699573 = 8699578
11 + 8699567 = 8699578
59 + 8699519 = 8699578
89 + 8699489 = 8699578
191 + 8699387 = 8699578
197 + 8699381 = 8699578
227 + 8699351 = 8699578
269 + 8699309 = 8699578

Showing the first eight; more decompositions exist.
