Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699472, here are decompositions:

29 + 8699443 = 8699472
53 + 8699419 = 8699472
59 + 8699413 = 8699472
83 + 8699389 = 8699472
163 + 8699309 = 8699472
179 + 8699293 = 8699472
193 + 8699279 = 8699472
233 + 8699239 = 8699472

Showing the first eight; more decompositions exist.
