Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699620, here are decompositions:

47 + 8699573 = 8699620
53 + 8699567 = 8699620
101 + 8699519 = 8699620
107 + 8699513 = 8699620
131 + 8699489 = 8699620
197 + 8699423 = 8699620
233 + 8699387 = 8699620
239 + 8699381 = 8699620

Showing the first eight; more decompositions exist.
