Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699778, here are decompositions:

7 + 8699771 = 8699778
47 + 8699731 = 8699778
137 + 8699641 = 8699778
167 + 8699611 = 8699778
211 + 8699567 = 8699778
239 + 8699539 = 8699778
277 + 8699501 = 8699778
359 + 8699419 = 8699778

Showing the first eight; more decompositions exist.
