Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699680, here are decompositions:

47 + 8699633 = 8699680
107 + 8699573 = 8699680
113 + 8699567 = 8699680
167 + 8699513 = 8699680
179 + 8699501 = 8699680
191 + 8699489 = 8699680
257 + 8699423 = 8699680
293 + 8699387 = 8699680

Showing the first eight; more decompositions exist.
